Thermodynamic and Kinetic Characterization of Porous Graphitic Carbon in Reversed‐Phase Liquid Chromatography
TL;DR: In this paper, the thermodynamics and kinetics of solute transfer on porous graphitic carbon (PGC) are studied for two series of aromatic hydrocarbons, alkylbenzenes and methylbenzenses, and the retention behavior is characterized as a function of temperature, pressure, length of alkyls chain and number and position of methyl substituents.

Reaction mechanisms in peptide synthesis part 2. tautomerism of the peptide bond
TL;DR: Using the MOPAC molecular orbital program, detailed geometric and energetic characteristics of the tautomerism of a peptide bond have been determined on the AM1 level and the inverse route is excluded as a possible initial step in the generation of a 5(4H)-oxazolone intermediate.

Reaction mechanisms in peptide synthesis. Part 1. Semiquantitative characteristics of the reactivity of 2-methyl-5(4H)-oxazolone with water and ammonia in the gas phase and weakly polar media.
TL;DR: Detailed geometric and energetic characteristics of the elementary reaction pathways for the additions of water and ammonia to 2-methyl-5(4H)-oxazolone have been determined at the AM1 level, demonstrating that the additions must be parsed into a two-step mechanism involving formation of the α-hydroxyimine followed by tautomerization to the parent N-acetylamino acid or amide.
