The FTIR spectra of the 2[nu][sub 1] and [nu][sub 1] + [nu][sub 3] bands of ClO[sub 2] (OClO) have been recorded in the 2,000 cm[sup [minus]1] region, with an instrumental resolution of [approximately] 0.004 cm[sup [minus]1]. The spectra have been analyzed using a Hamiltonian which includes spin-rotation terms to provide the first high-resolution analysis of these bands. Around 1,900 transitions of [sup 35]ClO[sub 2] have been assigned in 2[nu][sub 1], and 1,100 transitions of [sup 35]ClO[sub 2] have been identified in [nu][sub 1] + [nu][sub 3]. By making use of all available data, accurate band centers, rotational constants, spin rotational constants, and a number of the [chi][sub rs] anharmonicity constants as well as [alpha] and [gamma] parameters have been obtained.
