Deuterium isotope effect on the atomic orbital alignment dependence in the reaction of the oriented Ar (P-3(2)) with CH3CN (CD3CN)
Atomic orbital alignment effect was observed for the CN (B-2 Sigma(+)) formation in the reaction of oriented Ar (P-3(2)) with CH3CN (CD3CN). The relative cross-sections for each magnetic M-J' substate in collision frame, o(H)(vertical bar MJ'vertical bar) for CH3CN and sigma(vertical bar MJ'vertical bar)(D) for CD3CN, were determined to be sigma(0)(H):sigma(vertical bar 1 vertical bar)(H):sigma(vertical bar 2 vertical bar)(H):sigma(0)(D):sigma(vertical bar 1 vertical bar)(D):sigma(vertical bar 2 vertical bar)(D) = 1.00:0.81:0.84:2.01:1.92:1.87. A significant atomic orbital alignment effect was observed. In addition, a notable deuterium isotope effect was observed on both the cross-section and the atomic orbital alignment effect.
