摘要：

The photoacoustic spectra of some trivalent rare earth ions in aqueous solutions were obtained by laser-induced photoacoustic spectroscopy (LIPAS). This method was suitable for the spectral measurements of extremely weak absorption such as a forbidden transition of rare earth ions in liquid. Compared with the absorption and emission spectra in the visible region, the photoacoustic spectrum offered complementary spectroscopic information, particularly with respect to the radiationless decay process. © 1979, American Chemical Society.
