The superconducting thermodynamic properties of V/sub 3/Si are calculated with the use of the tunneling results of Bangert, Geerk, and Schweiss (lambda = 2.21, ..mu.. = 1.13) and those of Kihlstrom (lambda = 0.9, ..mu.. = 0.1). It is found that Kihlstrom's result gives a good description of the thermodynamics, while the ..cap alpha../sup 2/F and the ..mu.. of Bangert et al. do not. This implies that ..mu.. is small and so spin fluctuations do not play a significant role. We also find that the tunneling ..cap alpha../sup 2/F with 0.8< or =lambda< or =2.21 does not describe well, within the standard theory, the observed far-infrared behavior of V/sub 3/Si.
