Light with shorter wavelengths and higher energy will have a larger wavenumber, while light that has longer wavelengths will have lower energy and wavenumbers. Mid-IR, near-IR, and far-IR Infrared light can be further divided into three categories: Near infrared (NIR), mid infrared (MIR), ...
导致了更弱的C-O键。这反映在IR谱中就是C-O振动峰的wavenumber变小了。
The wavenumber assignments have been made for the proline functional groups, viz. COOH, COO-, CNCCC ring, [NH2]+, (CH2), CCN and CH. In both crystals, two proline residues share one proton and become monoprotonated. The observed bands show that in both compounds one of the proline ...

The red shift of the NH stretching wavenumber in the infrared (IR) spectrum from the computed wavenumber indicates the weakening of the NH bond resulting in proton transfer to the neighbouring oxygen atom. The simultaneous IR and Raman activations of the CO stretching mode give the charge ...
