The subsequent weighted fit of experimentally assigned transitions was made with the Hamiltonian model which takes into account the resonance interactions between the studied vibrational states. The purpose of the fee is to recover costs associated such sites. A list of transitions with their line intensities in the region of 1550–1950 cm−1 for the four mentioned species is generated. High resolution analysis of the ν1+ν2/ν2+ν3 of sulfur dioxide. spectrum (can be printed in landscape orientation). infrared reference spectra collection. Copyright for NIST Standard Reference Data is governed by Values of these parameters, being re-calculated to the values of corresponding parameters of the 34S16O2, 32S18O2 and 32S16O18O species were used for calculation of line intensities in the ν1+ν2 and ν2+ν3 bands of these three isotopologues.

By means of an infrared prism‐grating spectrometer equipped with a multiple‐path cell, seventeen vibration‐rotation absorption bands of SO 2 have been observed and recorded.

The cross-sections of the SO 2 stretching vibrations ν 1, ν 3 and the combination band of ν 1 +ν 3 were obtained and found to be slightly different from their gas phase values. The high resolution infrared spectra of the 32S16O18O molecule were recorded for the first time with a Bruker IFS 120 HR Fourier transform interferometer and analysed in the region of 1550–1950 cm−1 where the bands ν1+ν2 and ν2+ν3 are located. Infrared spectroscopy … Notice: Except where noted, spectra from this collection were measured on dispersive instruments, often in carefully selected solvents, and hence may differ in detail from measurements on FTIR instruments or in other chemical environments. Edit - response to example added (question d) by OP. About 1050 and 1570 transitions were assigned in the experimental spectra with the maximum values of quantum numbers J max.
