In Fourier Transform Infrared (FTIR) spectroscopy, which type of vibration requires the most energy?
A.bending
B. stretching
C. twisting
Homework Answers
Option B is correct one.
Generally bending requires less energy than stretching vibrations and occur at longer wavelengths. The greater the energy, the larger the frequency and the shorter (smaller) the wavelength.
