The structures of four new-type amines drug molecules, 2-amino phenyl propane ( a) , 2-methyl-amine-1-phenyl propane (b), 7-methoxy-a-methyl-1, 3-two oxygen truxene heterocyclic amylene-5-ethylamine ( c) and 2,5-dimethoxy-a-methylphenylacetamide ( d) , were optimized by using the density functional theory B3LYP/6-31++G**method.Based on this, the gaseous thermodynamic properties, such as frequency, heat capacity, entropy, enthalpy and free energy, were calculated, and then their infrared spec-troscopy, electronic spectra and molecular orbital diagrams were obtained.The simulating patterns of the func-tional relations between temperature and the gaseous thermodynamic properties, i.e., the standard molar heat capacity Cpm , standard molar entropy Sm and standard molar enthalpy Hm , were given.
