Web1 apr. 2024 · CH 4 has fundamental vibrational modes in the infrared (IR), with the main H-CH 3 stretching modes approximately 3.4 μm and the H-CH 3 deformation modes between 6.8–7.5 μm. Combination bands and the harmonics of these modes make the CH 4 spectrum quite rich in the mid- and near-IR (NIR) regions. WebThe first type of vibration is nondegenerate, while the third type has a twofold degeneracy, and both the second and fourth types have threefold degeneracies [2]. Snapshot 1: symmetric stretching leading to an IR-inactive vibration. Snapshot 2: asymmetric stretching leading to an IR-active vibration. Snapshot 3: IR rotational-vibrational spectrum. periphery\\u0027s in
