INFRARED SPECTRA OF ADDITION COMPOUNDS OF HYDROGEN AND DEUTERIUM CYANIDES WITH SOME INORGANIC CHLORIDES

The infrared spectra of addition compounds, (XCN)m · YCln in which X is H or D, Y is B, Ti or Sb, m is 1 or 2 and n is 3, 4 or 6, have been measured in the region from 4000 to 250 cm-1. The observed spectra of XCN · BCl3 and XCN · SbCl5 have been assigned on the basis of C3v, and G4v symmetry, respectively. A normal co-ordinate analysis has been performed for XCN · BCl3, and the isotopic effect upon the normal frequencies and the co-ordination effect upon the shift of vibrational frequencies of the parent molecules have been discussed. © 1969.
