核磁共振ppt课件内容预览：Chapter 13 pptElectromagnetic Radiation Wavelength Molecular Spectroscopy We study three types of molecular spectroscopy A pictorial view of UVVis UVVis radiation is measured in nm (wavelength) IR Spectroscopy IR radiation is measured in cm-1 This is actually a frequency.Remember that frequency and wavelength are inversely proportional. NMR Spectroscopy NMR uses radiowaves, measured in MHz Nuclear Spin States Any atomic nucleus that has an odd mass, an odd atomic number, or both has a spin and a resulting nuclear magnetic moment. The allowed nuclear spin states are determined by the spin quantum number, I , of the nucleus. 核磁共振A nucleus with spin quantum number Ihas 2I+ 1spinstates. If I= 12, there aretwo allowed spin states
