Photoionization spectroscopy of Ga-rare gas complexes

“…This has been shown by Hackett and co-workers for Al-RG 8 and In-RG, 9 for Tl-RG by Stangassinger and co-workers 12,13 ͑RGϭAr, Kr, and Xe͒ and for BAr by Hwang and co-workers. 14 Future studies may be able to probe the nature of possible barriers in the higher 2 ⌺ ϩ states of Ga-RG complexes, as several are expected to lie within accessible wavelength regions.…”

“…[1][2][3][4][5][6][7][8][9][10][11][12][13][14][15] The group IIIA metals have a ground-state configuration of 2 P, which results in a corresponding 2 ⌸ molecular ground state for M-RG van der Waals complexes. In some cases there is significant spin-orbit splitting in the ground molecular state, and the bonding in the two component states may be noticeably different.…”

Experimental and theoretical study of the AlNe complex

“…For the heavier group 13-rare gas complexes ͑GaRg, 11 InRg, 12,13 and TlRg 14,15 ͒, the fluorescence intensities for electronic transitions out of the X 1 2 ⌸ 1/2 and X 2 2 ⌸ 3/2 states were comparable. This indicates that the two X 2 ⌸ spin-orbit states had similar populations in the free jet expansion, despite the large spin-orbit splittings in these complexes.…”

“…The molecular electronic state arising from the first excited doublet Al atomic asymptote, Al(4s 2 S), is designated B 2 ⌺ ϩ , as in the other group 13 rare gas complexes. 3,4,6,[10][11][12][13][14][15][16][17][18]20,21 As Al(3d 2 D) is the next higher atomic state, the electronic states arising from this asymptote are denoted C 2 ⌬, D 2 ⌸, and E 2 ⌺ ϩ . Following this ordering, we designate the state arising from Al(5s 2 S) ϩRg as H 2 ⌺ ϩ , in agreement with the notation of Fu et al 21 for AlKr.…”

“…Complexes of the lightest of these, boron, have been studied intensively in our laboratory. [3][4][5][6][7][8][9][10] While complexes of the heavier atoms in this group ͑Ga, 11 In, 12,13 Tl 14,15 ͒ have also been investigated, those involving aluminum have received the most attention. [16][17][18][19][20][21][22] Gardiner and Lester 16 reported the first observation of the AlAr complex using resonance enhanced multiphoton ionization ͑REMPI͒ through the B 2 ⌺ ϩ -X 2 ⌸ 1/2 electronic transition, which correlates with the Al atomic 4s←3p transition.…”
