Anew optical pumping mechanism is observed for dilute Yb 3+ impurities in a sinple crystal of yttrium ethyl sulphare at low temperatures. The polariza!ion of Yb3+ spins is reduced by illumination with near infrzrcd radiation. This reduction in spin polarization is caus'ed by escitation of molecular

It is theoretically predicted that the Cc electronic vertical excitations are metastable with respect to the electron ejection. The energies of the lowest %;, "EL, \*I;, 'IX;, 2 4 and 'Ae states evaluated using first-order correlation orbitals and the coupled cluster method are reported.
