The jet-cooled tilde{A}-tilde{X} origin band absorption spectra of the G_1G_2G_3 conformer of four β-hydroxyethyl-peroxy (β-HEP) isotopologues, β-HEP (HOCH_2CH_2OO), β-DHEP (DOCH_2CH_2OO), β-HEP-d_4 (HOCD_2CD_2OO), β-DHEP-d_4 (DOCD_2CD_2OO), have been recorded by a cavity ringdown apparatus with a laser source linewidth ˜70 MHz in the near IR region. The spectra of all four isotopologues have been analyzed and successfully simulated with an evolutionary algorithm, confirming the cyclic structure of the conformer responsible for the observed origin band. In addition, rotational constants in both the tilde{X} and tilde{A} states and the orientation of the transition dipole moment have been determined. The broadened linewidth of the absorption spectrum (Δν > 2 GHz) is due to the shortened lifetime of the tilde{A} state following its internal conversion back to the tilde{X} state. The variation of lifetime with deuteration suggests that the hydroxyl hydrogen is involved and the process likely occurs along the reaction path for conversion between the peroxy and peroxide isomers.
