Polarisation labelling transitions indicated 'vee' correspond to excitation series probed either with an argon ion laser in the D-X system , or with a dye laser in the B-X system. The corresponding probe resonances are listed below. ________________________________________ Laser line, nm D-X transition ________________________________________ 514.5 Q(95) 4-1 501.7 P(24) 3 - 3 496.5 Q(43) 3 - 1 P(53) 5 - 2 488.0 R(22) 7 - 1 P(103)10 - 0 476.5 P(8) 12- 0 ________________________________________ Dye laser probe transitions, in the B-X system. ________________________________________ Wavenumber (cm-1) B-X transition (wavenumber from wavemeter readings). ________________________________________ 16548.15 Q(86) 2-3 17103.17 R(42) 7-2 17103.23 Q(40) 7-2 17106.12 P(53) 8-2 Gave lambda transitions from J44 e v = 28 " P(37) 7-2 17108.28 Q(38) 7-2 Gave lambda transitions " R(40) 7-2 (weak) 17129.68 R(30) 7-2 17129.71 P(34) 3-0 " P(56) 4-0 R(39) 3-0 17135.38 R(36) 3-0 17159.13 Q(63) 10-2 17159.13 Q(16) 3-0 17164.52 Q(47) 4-0 17164.52 Q(69) 8-1 17164.52 Q(8) 3-0 17284.38 R(43) 14-3 17284.38 R(30) 13-3 Gave lambda transitions D-X v' 19, J' 71 17284.44 Q(88) 11=0 Gave lambda transitions from J30 f, v = 22, J71e, v19,J 86 e, v= 17, J 50 e, v= 20 with circ. pol. 17284.59 P(57) 7-0 17399.69 P(84) 14-0 ________________________________________
