The high resolution infrared spectrum of the 34S16 O2 molecule was re-investigated in the region of 1600-1900 cm-1. The earlier studied by Lafferty et al., the ν2+ν3 band was re-analyzed under consideration of transitions with higher values of quantum numbers J and Ka. The weak ν1+ν2 cold band and the 2ν2+ν3-ν2 hot band were analyzed for the first time. The obtained experimental data were used in the weighted fit procedure based on the effective Hamiltonian which takes into account resonance interactions between a variety of vibrational states. The obtained set of spectroscopic parameters reproduces the initial experimental data with accuracies close to experimental uncertainties.
