1,2-Didehydronaphthalene (1-naphthyne) was produced in a low temperature argon matrix by wavelength-selective photolysis of 1,2-naphthalenedicarboxylic anhydride, which was confirmed by comparison of its FTIR spectrum with the theoretical IR spectrum calculated by density functional theory.
C moiety showed relatively large
deviation, the rms deviation between calculated (scaled by 0.961414)
and observed1a frequencies was 40.7 cm–1.
