THE NATURE OF ULTRAVIOLET SPECTROSCOPY

The term UV spectroscopy generally refers to electronic transitions oeeurring in the region of the electromagnetic spectrum (A, in the range 200-380 nm) aeeessible to standard UV spectrometers. [Pg.8]

Electronic transitions are also responsible for absorption in the visible region (approximately 380-800 nm) which is easily accessible instrumentally but of less importance in the solution of structural problems, because most organic compounds are colourless. An extensive region at wavelengths shorter than 200 nm ( vaeuum ultraviolet ) also corresponds to electronie transitions, but this region is not readily accessible with standard instruments. [Pg.8]

UV spectra used for determination of structures are invariably obtained in solution. [Pg.8]
