Extreme mode selectivity in a dissociating van der Waals molecule: complexes of aminotetrazine and argon

The photodissociation of aminotetrazine-Ar and aminotetrazine-Ar2 was studied using supersonic jet spectroscopy. Excitation of aminotetrazine-Ar to the levels 16b2, 16a2, and 6a1 (429, 505, and 606 cm−1 vibrational energy, respectively) produced photodissociation lifetimes that differed by more than...

Description
Summary:The photodissociation of aminotetrazine-Ar and aminotetrazine-Ar2 was studied using supersonic jet spectroscopy. Excitation of aminotetrazine-Ar to the levels 16b2, 16a2, and 6a1 (429, 505, and 606 cm−1 vibrational energy, respectively) produced photodissociation lifetimes that differed by more than two orders of magnitude. Excitation of these three levels in aminotetrazine-Ar2 caused large changes in the branching ratio between the two dissociation products, aminotetrazine-Ar and aminotetrazine.
