摘要：

By computer simulation of experimental dynamic gas chromatographic elution profiles, the rotational energy barrier Delta G(=) of racemic 2,2'-diisopropylbiphenyl has been determined as 114.6-115.0 kJ/mol (75-100 degrees C). These data are in good agreement with a value that was determined previously by measuring the racemization kinetics of an enriched sample. This indicates that there is no measurable catalytic or inhibitory effect of the stationary phase. (C) 1994 Wiley-Liss, Inc.
