## Measurement and assignment of the i.r. and Raman spectra of trans,transand c&tram-2,4hexadienes were carried out. The normal coordinate analyses of these two isomers were done to obtain a force field transferable to 1,4-diphenyl-traqtrans-1,3-butadiene and transand cis-polyacetylenes.
Normal coordinate treatment was carried out for the orthonitrate anion NOato investigate the vibrational force field and the normal modes of internal vibration. Based on the differences between the observed and calculated fundimem-t&l wavenumbers, the inter a1 tension K(NO -) was found to be a h m 8
Normal coordinate analyses for 2-, 3-and 4-acetylpyridine and acetophenone were carried out employing a systematic procedure based on a modified valence force field that is comparable to those used previously for different aromatic molecules. The general valence force fields (GVFF) were determined u
