WebDec 1, 2024 · Ethane has a total of 12 fundamental modes of which five are infrared (IR) active. The main wavelength regions are around 12 µm (800 cm −1 ), 7 µm (1400 cm −1 ) and, the strongest, around 3 µm (3000 cm −1 ), where two active CH stretching modes are present (ν5 and ν7) [20] . WebEthane has a complicated spectrum (many interacting vibrational modes), which makes it difficult to accurately predict the spectrum. The 2900 cm-1 region is particularly messy …

WebAn IR-active vibrational transition occurs only when the vectorial sum of the individual C-H bond dipoles undergoes a change. If there is no such change in the dipole moment, the vibration is IR inactive, but still possibly active in the Raman spectrum. Each type of vibration is classified according to the symmetry group of the molecule [1]. [more] WebSince it has even more atoms, it's vibrations are even more complicated. The Infrared spectrum of methane is shown below. The animations are listed by the CALCULATED frequency. Can you figure out which vibrational modes are IR active?
