Pj. Deren et al., COMPARATIVE-STUDIES OF VIBRONIC TRANSITIONS IN ONE-PHOTON AND 2-PHOTON SPECTRA OF GD3+ IN CS2NAGDCL6, Acta Physica Polonica. A, 90(2), 1996, pp. 295-300
Vibronic spectra of Gd3+ in Cs2NaGdCl6 were measured under one- and tw
o-photon excitations. Following the vibrational analysis of the Cs2NaG
dCl6 crystal an assignment of vibronic transitions was proposed. It wa
s found that the vibronic transitions in one- and two-photon spectra a
re combined with the odd parity modes.
