The spectra of vibrationally hot HOI formed in the reaction of alkyl iodides with oxygen atoms are observed by Fourier transform infrared emission spectroscopy. The {ital v}=1{endash}3 levels of the OH stretch are observed via the {Delta}{ital v}={minus}1 and {Delta}{ital v}={minus}2 sequence bands. The spectrum of DOI is observed by using 2,2,2-{ital d}{sub 3}-iodoethane as the precursor in the oxygen atom reaction. The {ital v}=1{endash}4 levels of the OD stretch are observed in the {Delta}{ital v}={minus}1 sequence band, and the {ital v}=1{endash}5 levels of the OD stretch are observed in {Delta}{ital v}={minus}2. Medium resolution spectra (0.031 cm{sup {minus}1} apodized) are recorded and rotationally analyzed for the {nu}{sub 1} fundamental and 2{nu}{sub 1}{minus}{nu}{sub 1} hot band of HOI. An estimate of the HOI ground state structure is made by constraining the OH bond length to its value for HOCl and HOBr and calculating the HOI bond angle and the OI bond length by least squares fit to the ground state rotational constants. {copyright} {ital 1996 American Institute of Physics.}
