We do not, however, give reasons for the assessors choice nor are details given of experimental techniques. Where alternative values for a given standard enthalpy of formation may be derived, from independent measurements, we have clearly indicated those which are regarded by the assessors as definitive and which are therefore used to derive the value for the compound concerned. The experimental data used in the computer calculation of the values for standard enthal pies of formation are clearly indicated in Table 1.2. ![]() ![]() Data presented in the book are stored in a data base at the University of Sussex and with associated software provides a simple but efficient method for dealing with thermochemical problems in organic chemistry. Chapter 1 contains tables of values for standard enthalpies of formation derived from experimental data for approximately 3000 organic compounds of the elements C, H, 0, N, S and halogens Chapters 2 to 4 describe a simple scheme for predicting unknown values of standard enthalpies of formation. ![]() The purpose of the material in this book is to enable users of thermochemical data to predict values for standard enthalpies ofreactions involving organic compounds ranging in complex ity from simple alkanes to biologically important compounds such as amino acids.
