Vibrational Spectra and Analysis of Trans – decahydronaphthalene 

By P.Mani and S.Suresh 


FTIR and FTR spectra of Trans-Decahydronaphthalene have been recorded in the regions 200 - 4000 cm-1 and 30- 4000 cm-1. The vibrational analysis has been carried out by assuming Cs symmetry. The observed frequencies were assigned to various modes of vibrations on the basis of intensity, frequencies from allied molecules and the normal coordinate calculations. The potential energy distributions associated with normal modes are also reported here. The assignment of fundamental vibrational frequencies for Trans- Decahydronaphthalene agree with the calculated frequencies.
