The vibrational spectrum and antifungal activity of 3,4,5-trimethoxybenzald
ehyde thiosemicarbazone have been reported. The thermodynamic functions hav
e been calculated using the IR frequencies. The group sensitive fundamental
s are compared with those of similar molecules already reported in the lite
rature. The-antifungal activity of the said compound has been screened agai
nst Rhizopus, Aspergillus nidulence, Aspergillus flavus, Aspergillus niger
and Alternaria alternate.
