摘要：
The TcC(g) molecule is observed above a liquid technetium carbide phase of unknown composition by using Knudsen effusion mass spectrometry. Intensity data for Tc(g) between 2229 and 2560 K and for TcC(g) between 2393 and 2595 K give a third-law bond energy of D°0 = (134 ± 7) kcal mol-1 for TcC(g). A value of D°0 = (140 ± 2) kcal mol-1 is obtained by the second-law method. © 1979 American Chemical Society.
