Determination of Thermodynamic Functions for the Hydrogen Bonded Complexes Pyrrole-DMSO and Indole-DMSO

Abstract

수소결합착물인 Pyrrole-DMSO와 Indole-DMSO에 대한 수소결합생성엔탈피를 순염기열계량법, 고희석열계량법 및 적외선분광법으로 측정하여 비교하였다. DMSO가 극성이 큰 물질임에도 불구하고 수소결합착물의 생성엔탈피 값들은 측정방법에 의한 차이가 크지 않았다.

The enthalpies of formation for the hydrogen bonded complexes Pyrrol-DMSO and Indole-DMSO have been determined by the pure base and high dilution calorimetric methods and by IR spectroscopy. The agreement between all three methods for the enthalpy of the hydrogen bonded adducts is good, though it is considered that DMSO is a highly polar solvent.
