Mixing of symmetry coordinates in methyl cyanide and methyl isocyanide

A large change in the contribution of different symmetry coordinates to normal coordinates can cause some frequencies to increase when deuterium is substituted in certain molecules. This point is discussed and applied to the assignments of methyl- d 3 cyanide, methyl- d 3 isocyanide and deuterated m...

Description
Summary:A large change in the contribution of different symmetry coordinates to normal coordinates can cause some frequencies to increase when deuterium is substituted in certain molecules. This point is discussed and applied to the assignments of methyl- d 3 cyanide, methyl- d 3 isocyanide and deuterated methyl acetylenes.
