Electronic and vibrational spectra of diphenylmethane

Online monitoring of synthesis and curing of phenol–formaldehyde resol resins by Raman spectroscopy

“…The vibrational spectrum of 2-benzylphenol has been interpreted in the literature [34]. The literature assignments for diphenylmethane [35,36] and bis(2-hydroxyphenyl)methane [37], in addition to Raman group frequency tables [38,39], were used to assist the interpretation of the Raman spectra of the model compounds.…”

DFT calculation and Raman excitation profile studies of benzophenone molecule

“…In assigning the vibrational frequencies of BOP molecule, the visual inspection of the normal modes animated from the output files of DFT calculations using Gauss View 3.0 and Molekel 4.2 program have been conducted. The availability of the literature concerning the vibrational assignments of this [42] and related molecules [13][14][15][16][17][18][19] have also been consulted.…”

“…But in case of non-resonant excitation, contributions from several electronic states to Raman intensities might be significant. For such kind of excitation, extensive investigations of REPs are found to be very helpful in getting structural insights and in studying many other interesting properties of molecules in different excited electronic states [13][14][15][16][17][18][19][20].…”

“…As Raman excitation lies in a region not close to any excited electronic state, the contributions from several electronic states might be important in the scattering process [29][30][31]. So in this communication, experimental findings have been found to be simulated satisfactorily by using sum-over-states (SOS) method based on pertinent Franck-Condon and vibronic (Herzberg-Teller) www.elsevier.com/locate/vibspec Vibrational Spectroscopy 44 (2007) [331][332][333][334][335][336][337][338][339][340][341][342] coupling terms [13][14][15][16][17][18][19][20]. Previously Kamei et al [32] also showed that the confirmation of BOP is affected by electronic excitation from the ground electronic state.…”

Vibrational spectroscopic analysis of 2-chlorotoluene and 2-bromotoluene: A combined experimental and theoretical study

“…Various spectroscopic studies of halogen and methyl substituted compounds have been reported in the literature from time to time [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. Green and Dwivedi have studied the vibrational spectra of few dihalogenotoluenes of TXY type toluenehalogens [3,4].…”
