Notes on molecular orbital calculations by John D Roberts( Book )

For practicing organic chemists the simple, linear-combination-of-atomic-orbitals (LCAO), molecular-orbital method permits useful calculations of semi-empirical electronic energies of unsaturated molecules with no more than high school algebra. Anyone who can find the roots of x^4 - 5x^2 + 4x = 0 graphically, analytically, or by successive substitutions can obtain the energy levels and calculate the [Greek pi]-electron energy of bicyclo[1.1.0]butadiene. [figure of bicyclobutadiene] If in addition he can solve x^4 - 4x^2 = 0, then he can compare bicyclobutadiene with cyclobutadiene and predict what changes the 1, 3 bond would make in the a-electron energies. With no more advanced mathematics, one can compute the bond orders, charge distributions, and reactivity parameters for both free-radical and polar processes. The results may be crude, but they are often highly suggestive; there is no excuse for a modern organic chemist not to be able to use the LCAO method. The notes that make up this book have been used for many years at the California Institute of Technology to introduce seniors and graduate students to the elements of the simple LCAO method. A fairly large number of exercises are interspersed in the text to illustrate important points. It is recommended that these be solved as encountered. Some of the problems are hoped to be suggestive of possible research problems in the field. These Notes are not intended as a complete course of study and should be supplemented by the reference works listed in the Bibliography. No attempt has been made to survey the recent literature. The purpose has been to provide a practical introduction. As a result no appropriate acknowledgement to either the priority of ideas or to their development has been given
Nuclear magnetic resonance; applications to organic chemistry by John D Roberts( Book )

28 editions published between 1959 and 1963 in 7 languages and held by 844 WorldCat member libraries worldwide

This brief book is the outgrowth of some forty lectures in which it was attempted to explain the phenomenon of nuclear magnetic resonance absorption and the uses of high-resolution nuclear magnetic resonance spectroscopy to organic chemists whose background, like that of the author, has often been deficient in nuclear and electromagnetic theory. Quite a number of suggestions were received for presentation of the material in printed form with illustrations based on the lecture slides. This has now been done, and it is hoped that the result will be of service to practicing chemists and students as a guide to various applications of NMR spectroscopy and an introduction to more authoritative works. Throughout, the coverage is illustrative rather than comprehensive
An introduction to the analysis of spin-spin splitting in high-resolution nuclear magnetic resonance spectra by John D Roberts( Book )

35 editions published between 1961 and 1964 in 4 languages and held by 751 WorldCat member libraries worldwide

To learn to apply the methods of wave mechanics in a practical way seems to involve a quantum-like transition with a relatively low transition probability. Chemistry students by the thousands are exposed to the principles and jargon of wave mechanics and are able to talk in a most knowing way about orbitals, overlap, spin, etc. But very few of these students can set about to make any sort of an actual calculation of resonance energies of conjugated systems or the energy levels of nuclear spin systems, and this despite the fact that the mathematics involved, although perhaps tedious, usually does not require more than college algebra. I lay the blame for this situation just as much on the writers in the field and the students themselves as on the intrinsic difficulties of the subject. Many writers seem sincerely anxious to impart their knowledge to novices but may have forgotten, or never really knew, how difficult it is for the average chemist to make the transition between knowing and not knowing. Certainly, it is a long and tedious job to try to make clear in writing step by step what is involved, particularly when exciting prospects of discussing applications and new developments beckon. Students in their turn make things hard for themselves by their failure to work problems or to work through even simple derivations. Although it may seem presumptuous to some readers for a synthetic organic chemist to write an introduction to the quantum mechanical formulation of nuclear spin states and transitions, I have pointed out elsewhere [J. Am. Chem. Soc., 82, 5767 (1960)] that I believe all chemists can use nuclear magnetic resonance spectroscopy with greater interest, skill, and understanding by having at least a rudimentary knowledge of the quantitative theory of spin-spin splitting. The purpose of this book is to show that the path to making practical calculations of spin-spin splittings is not really difficult
Organic chemistry : methane to macromolecules by John D Roberts( Book )

40 editions published between 1971 and 1976 in English and Undetermined and held by 350 WorldCat member libraries worldwide

In the present work we have tried to paint an interesting, relevant, and up-to-date picture of organic chemistry while retaining the rigorous approach of the earlier books. Organic chemistry sometimes appears to be enormously complex to the beginning student, particularly if he must immediately grapple with the subjects of structural isomerism and nomenclature. We have attempted to avoid this difficulty in the following way. Chapter 1 briefly relates carbon to its neighbors in the Periodic Table and reviews some fundamental concepts. Chapter 2 deals with the four C1 and C2 hydrocarbons-methane, ethane, ethene, and ethyne-and discusses their conformational and configurational properties and some of their chemical reactions. The reader thus makes an acquaintance with the properties of some important organic compounds before dealing in an open-ended way with families of compounds-alkanes, alcohols, etc. A heavy emphasis on spectroscopy is retained but the subject is introduced somewhat later than in the earlier books. Important additions are chapters dealing with enzymic processes and metabolism and with cyclization reactions. Many of the exercises of the earlier books have been retained and have been supplemented with drill-type problems. It seems a shame to burden the mind of the beginning student with trivial names, some of them quite illogical, and throughout we have stressed IUPAC nomenclature, which is both logical and easy to learn. The instructor, who may well carry lightly the excess baggage of redundant names, may occasionally find this irritating but we ask him to consider the larger good. As a further aid to the student, each chapter concludes with a summary of important points. The simple introduction to the subject and the emphasis on relevance, particularly to living systems, should make the book appealing to the general student. At the same time we hope that the up-to-date and more advanced topics that are included-the effect of orbital symmetry on cyclization reactions, for example-will also appeal to the chemistry specialist
