Abstract
Abstract Infrared spectra have been obtained and normal coordinate calculations performed for 2,3,4-trimethylpentane and 2,3,4-trimethylhexane with force constants that had previously been determined for several other trimethylalkanes. 2,3,4-TMP exists in only one possible spectroscopically distinct conformation, but 2,3,4-TMH was found to exist as two diastereomers, each of which exists in two conformations. The average difference between observed and calculated frequencies for 212 assigned values of the five molecules is 4.2 cm −1 .
