摘要：

The change of spectroscopic properties of sodium-watek and sodium-ammonia complexes upon deuteration is investigated. The ionization potential of NaD2O is shifted by 70 cm(-1) towards lower energies compared to NaH2O. A shift of 81 cm(-1) between NaND3 and NaNH3 is observed again towards lower energies. From these shift the vibrational frequencies for the ground state of the neutral and ionic complex have been estimated. The first electronically excited state ((A) over tilde(2)E) of NaND3 has been investigated by resonant two color two photon ionization. The comparison with the formerly observed NaNH3 spectrum enables us to do an unequivocal assignment of the vibrational structure. (C) 1997 American Institute of Physics. [S0021-9606(97)01646-2].
