Conformational analysis through selective isotopic substitution: supersonic jet spectroscopic determination of the minimum energy conformation of o-xylene

Abstract

Supersonic jet mass resolved excitation spectroscopy is employed to observe the S1â†� S0 electronic transition origin of the individual conformations of [α-2H1]-, [α,α-2H2]- and [α,α′-2H2]-o-xylene and to establish the minimum energy conformation of o-xylene in its ground (S0) and first excited (S1) singlet states. The anti, planar, gear clashed conformer 5[see Tables 1 and 2; i.e., τ(C-2–C–1-Cα–H-α)=τ(C-1–C-2–C-α′–H-α′)= 180°] is found to be the most stable.
