- •
The CN-stretching frequencies in DHA and VHF dissolved in CS2 were not affected by substitution.
- •
CN-stretching frequencies in DHA redshift upon ring-opening to VHF.
- •
CN-stretching frequencies in DHA split into two separate bands upon ring-opening to VHF.
- •
The calculated frequency shifts and intensity changes upon ring-opening are in agreement with the experimental observations.
