Vibrational spectrum of malononitrile and thermodynamic properties

Vibrational spectrum of malononitrile was measured Assignment of the frequencies to the fundamental modes of vibrations has been made. Teller-Redlich product rule was employed to check the assignment. Thermodynamic functions were calculated from spectroscopic data

Physicochemical studies on phenanthroline metal complexes

Complexes of 1,10-phenanthroline [phen] with transition metal ions were prepared. Complexes of the type [M[phen]3]X.H2O were obtained. The electronic and vibrational spectra of these complexes indicate that these complexes are octahedrally coordinated. Crystal field parameters were calculated from transition energy diagrams. Magnetic moments of these complexes were determined. Thermal conductivity data indicate that these complexes behave as semi conducting materials. This work might well make the first part of a worthwhile study
