Journal ArticleDOI
An improved force field (MM4) for saturated hydrocarbons
TL;DR: In this paper, a new force field has been developed for alkanes and cycloalkanes, excluding small rings, to improve the calculation of vibrational frequencies, rotational barriers, and numerous relatively small errors that were observed to result from the use of the MM3 force field.

Journal ArticleDOI
A comprehensive study of the rotational energy profiles of organic systems by ab initio MO theory, forming a basis for peptide torsional parameters
TL;DR: Ab initio molecular orbital calculations have been carried out on over 50 model organic molecules and ions to provide the data necessary in the determination of torsional parameters for a force field involving polypeptides.

Thermolabile Kohlenwasserstoffe, IV: Tetra‐tert‐butylethan
TL;DR: The most thermolabile alkane hydrocarbon known at present is tetra-tert-butylethane (3,4-di-terth-butyl-2,2,5,5-tetramethylhexane) as mentioned in this paper.
