The 3H4~3P o transition in the absorption spectra of Pr 3+ in the hexachloroelpasolites Cs2NaPrxY~\_xCl6 (X=0.1 to x= 1 ) have been measured from 300 to 10 K. The electronic spectra are dominated by electric-dipole allowed vibronic origins enabled by Herzberg-Teller coupling. The two odd parity vibr
