Abstract

The (B) over tilde (1)A(1) <- (X) over tilde (1)A(1) electronic band system of the protonated diacetylene cation (H2C4H+) is measured over the 230-295 nm range by photodissociating H2C4H+ ions stored in a cryogenic ion trap and by photodissociating H2C4H+ tagged with Ar and N-2 in a tandem mass spectrometer. The H (B) over tilde (1)A(1) <- (X) over tilde (1)A(1) band system has an origin at 34 941 cm(-1) for H2C4H+, 34 934 cm(-1) for H2C4H+-Ar, and 34 920 cm(-1) for H2C4H+-N-2. The spectra of H2C4H+, H2C4H+-Ar, and H2C4H+-N-2 display similar vibronic structure, which is assigned using ab initio calculations to progressions in two symmetric a(1) C-C stretch vibrational modes (v(6) and v(4)), with band spacings of 860 and 1481 cm(-1), respectively.
