Formation and phase transition enthalpies for captopril

Abstract Combining solution calorimetry data with quantum chemical thermochemistry, a series of thermochemical parameters for captopril were obtained, as follows:  ΔsolHθ (in water) = 12.26 ± 0.4kJmol-1; ΔsolvHθ= -53.43kJmol-1crgHθ = 65.70 kJmol-1, ΔcrlHθ= 19.53kJmol-1lgHθ= 46.17 kJmol-1fgHθ= -623.10 kJmol-1, ΔflHθ = -576.93 kJmol-1;   ΔfcrHθ= -557.40  kJmol-1; Cv= 231.72 JK-1mol-1andCp= 240.03 JK-1mol-1.
