โœฆ Synopsis


Abstract

Studies have been carried out on alkyl peroxides with MM3 that have led to a parameter set that allows the calculation of geometries, energies, vibrational frequencies, and heats of formation for alkyl hydroperoxides (R๏ฃฟO๏ฃฟO๏ฃฟH) and dialkyl peroxides (R~1~๏ฃฟO๏ฃฟO๏ฃฟR~2~). The results obtained are in agreement with the available experimental and theoretical data. A similar, although less good, parameter set has been developed for MM2. ยฉ 1993 John Wiley & Sons, Inc.

The conformat ions of various cyclic peroxides have been determined using a molecular mechanics force field developed by the authors and previously applied to linear peroxides. Comparison of the results with those of experimental and ab initio studies shows that this force field may be employed with

A force field has been developed for use in MM2 calculations of geometric and energy data for linear peroxides R1--O-O-R2 and tested in some of them (R1, R2 = H, Me, Et, Pr', But). The field obtained yield results that agree considerably better with experimental and ab initio data than those afford

## Abstract The MM4 force field has been extended to include aliphatic amines. About 20 amines have been examined to obtain a set of useful molecular mechanics parameters for this class. The vibrational spectra of seven amines (172 frequencies) calculated by MM4 have an overall rms error of 27 cm^โˆ’

Myelin basic protein (MBP) is the major extrinsic protein of the myelin sheath in the central nervous system. We have examined the predicted structure of segments of MBP using the molecular mechanics program ECEPP83 developed by Scheraga and coworkers as modified by Chuman, Momany, and Schafer. We h
