The electronic transitions in these molecules arise from a predominantly metal-centered electron. Therefore, the low resolution spectra of these species show characteristic features (spin-orbit splittings, vibrational frequencies. . . ) which changes little when the ligand is changed. The simple one-electron model usually used to describe diatomic alkaline earth halides (CaF, SrF. . . ) will be shown to be applicable to the polyatomic derivatives. A general discussion of these spectral and structural similarities, as well as methods to produce and detect theses species will be presented. Then the high resolution spectrum of the C2A1-X2A1 transition of CaNH2, generated in a laser ablation/molecular beam spectrometer, will be discussed. The simple pure precession model will be derived for polyatomic species and applied to predict the spin-rotation interactions in the CaNH2 molecule. The second part deals with the high resolution infrared emission spectra of metal-containing diatomic molecules, InF and the coinage (Cu, Ag, Au) metal hydrides. The high temperature Fourier transform infrared spectra of these molecules are recorded at high resolution to derive accurate molecular constants. The data analysis is carried out using standard procedures (Dunham model) and also be directly solving the radial Schodinger equation. In this way, an effective Born-Oppenheimer potential is determined by fitting many isotopomer data to an equation containing a parameterized potential function. The potentials derived in this manner are superior to standard methods for predicting various molecular properties.application/pdf10391361 bytesapplication/pdfenCopyright: 1997, Morbi, Zulfikar.
