3 Terms and Definitions
GB/T 13966 and established in the following terms and definitions apply to this section.
3.1
Wavelength (wave number) and the absorbance in the ultraviolet or visible substance depict region (200nm ~ 700nm) resulting absorption curve.
3.2
Interaction of light research material elements of ultraviolet and visible wavelength region, the absorbance using an absorption wavelength band performed the sample position
The qualitative and quantitative analysis.
3.3
Picture guide function is the derivative spectrum, there is a first, second, third and other derivative spectra.
3.4
UV and visible regions of the same type of transition, said absorption peak absorption band can be divided into R band, K band, B and E with a belt.
3.5
Beside a meandering peaks generated by Sh he represents.
3.6
Also known as the long shift, due to the local structure of the compounds or modified to use when ultraviolet and visible absorption solvent change to the longer wavelength direction mobile.
3.7
Also known as short-shift, due to the local structure of the compound modification or change when the solvent used ultraviolet and visible absorption peak shifts to shorter wavelengths.
