“…Randle and Whiffen [19] assigned the symmetric stretching .frequency to a band lying between 1333 and 1370 cm -1 and the antisymmetric frequency between 1494 and 1539 cm-1 in the spectra of aromatic nitrobenzene derivatives. In the present case e have assigned the strong bands at 1355 and 1525 cm-1 (Table H) to ΝO2 symmetric and asymmetric stretching vibrations, respectively, in accordance with the assignments made by Mooney [7], Kishore et al [20] and Singh and Rai [21]. In the Raman spectrum the symmetric vibration has appeared very strongly at 1340 cm-1 but asymmetric vibration has occurred weakly at 1525 cm-1 .…”

“…The observed wave number of the bands along with their vibrational assignments are listed in tables 2 and 3. The determined constants are in close agreement with the earlier reported values [3,5,8,10]. The comparison between reported values and present study is given in table 1.…”

“…Nampoori and Patel [4] recorded the spectra on 2 m plane grating spectrograph (PGS-2) at a dispersion of 0.5Å/mm. Vibrational constants reported by Singh et al [5] agree with those of Lakshminarayana and Harnath [3] but their reported values of vibrational heads do not match with each other. They also reported predissociation in A 3 Π 0 state.…”

“…Burnecka and Zyrnicki's [10] study shows that the data obtained from their constants do not match with the reported spectrum. Apart from this, the rotational structure of A 3 Π 0 -X 1 Σ + and B 3 Π 1 -X 1 Σ + systems, the Rydberg-Klein-Rees (RKR) curve and the Franck-Condon factor [11,12], rotational [13][14][15] and nuclear quadrupole [16] coupling constants of the ground state of InBr were determined.…”

The emission spectrum of InBr molecule has been recorded in the region 350-400 nm on BOMEM DA8 Fourier transform spectrometer at an apodized resolution of 0.06 cm −1 using microwave excitation technique. About 61 violet degraded and single headed bands have been recorded and are classified into two band systems, viz. A 3 Π0-X 1 Σ + and B 3 Π1-X 1 Σ + . A few new bands have been observed and are fitted in the vibrational schemes of the two systems. Revised vibrational constants have been determined. The vibrational assignments have been confirmed by observing isotope effect due to InBr 81 in the 30 bands of the A 3 Π0-X 1 Σ + system and 19 bands of the B 3 Π1-X 1 Σ + system. The analysis is further supported by calculating the Franck-Condon factor for InBr 79 and InBr 81 molecules. The following vibrational constants (in cm −1 ) have been determined from the analysis:A 3 Π0-X 1 Σ + system: ν00 = 26599.1 ω e = 226.42, ω e x e = 1.24 cm −1 , ω e = 221.19, ω e x e = 0.528 cm −1 . B 3 Π1-X 1 Σ + system: ν00 = 27380.52 ω e = 223.086, ω e x e = 1.446 cm −1 , ω e = 221.19, ω e x e = 0.528 cm −1 .

“…The simulation requires vibrationally resolved Franck-Condon factors (F CF ) and transition probabilities A v ′ v ′′ ik as input parameters. F CF of the InBr molecule can be found in literature only for vibrational quantum numbers up to v = 13 [18] and radiative lifetimes can be found only for selected vibrational levels of the A or B state [8]. Therefore F CF and A v ′ v ′′ ik were calculated using the program TraDiMo [19].…”

Inductively coupled low pressure discharges containing InBr have been investigated spectroscopically. In order to obtain plasma parameters such as the vibrational and rotational temperature of the InBr molecule, the emission spectra of the A 3 Π 0 + → X 1 Σ + 0 and the B 3 Π 1 → X 1 Σ + 0 transitions have been simulated. The program is based on the molecular constants and takes into account vibrational states up to v = 24. The required Franck-Condon factors and vibrationally resolved transition probabilities have been computed solving the Schrödinger equation using the Born-Oppenheimer approximation. The ground state density of the InBr molecule in the plasma has been determined from absorption spectra using effective transition probabilities for the A − X and B − X transition according to the vibrational population. The obtained densities agree well with densities derived from an Arrhenius type vapour pressure equation.
