The CN stretching band of aliphatic thiocyanate is sensitive to solvent dynamics and specific solvation
Abstract:
Infrared absorption spectra in the C[triple bond]N stretching frequency region were collected for methyl thiocyanate, the simplest model aliphatic thiocyanate, in several common solvents to establish the dependence of the C[triple bond]N spectral band of aliphatic thiocyanate on its local solvation environment. Systematic changes in the C[triple bond]N bandwidth indicate that it reports on fast solvation dynamics. Anomalous asymmetry and temperature dependence of the C[triple bond]N band in fluorinated alcohol solvents indicates that these solvents participate in formation of a discrete hydrogen-bonded complex with the C[triple bond]N end of methyl thiocyanate. These observations indicate that the C[triple bond]N band of thiocyanate could be an effective site-specific probe of both specific hydrogen bonding and local dynamics in more complex systems, such as peptides and proteins.

IR Frequency Region: Alkyne and Nitrile Stretching
Comparing the stretching vibrational frequency of C≡C triple bonds with that of double and single bonds, it is evident that C≡C triple bonds exhibit a higher stretching frequency than C=C double and C–C single bonds. Similarly, the C≡N triple bond exhibits higher stretching absorption than the C=N...
