چکیده
The S1←S0 00 transitions of phenol and the hydrogen bonded phenol~H2O!1 cluster have been studied by high resolution fluorescence excitation spectroscopy. All lines in the monomer spectrum are split by 5664 MHz due to the internal rotation of the 2OH group about the a axis. The barrier for this internal motion is determined in the ground and excited states; V29 5 1215 cm , and V2854710 cm . The rotational constants for the monomer in the ground state are in agreement with those reported in microwave studies. The excited state rotational constants were found to be A855313.7 MHz, B852620.5 MHz, and C851756.08 MHz. The region of the redshifted 00 0

Picosecond IR-UV pump-probe spectroscopic study of the dynamics of the vibrational relaxation of jet-cooled phenol. II. Intracluster vibrational energy redistribution of the OH stretching vibration of hydrogen-bonded clusters.
A picosecond time-resolved IR-UV pump-probe spectroscopic study has been carried out for investigating the intracluster vibrational energy redistribution (IVR) and subsequent dissociation of hydrogen-bonded clusters of phenol (C6H5OH) and partially deuterated phenol (C6D5OH, phenol-d5) with various solvent molecules. The H-bonded OH stretching vibration was pumped by a picosecond IR pulse, and ...
متن کاملTorsional barriers in aromatic molecular clusters as probe of the electronic properties of the chromophore.
We present a computer program that is capable of fitting n-fold torsional barriers Vn (n = 2-6) and torsional constants F simultaneously to high- and low-resolution spectroscopic data of different isotopomeric internal rotors. The program has been utilized to fit independently barriers and torsional constants for both electronic states of several aromatic clusters. The constant F of the ammonia...

The trinuclear arene–ruthenium cluster cation [H3Ru3(C6H6)(C6Me6)2(O)] þ, containing a l3-oxo cap and three arene ligand that span a hydrophobic pocket above the metal skeleton, has been crystallised as tetrafluoroborate salt in the presence of variou guest molecules. The host–guest complexes have been characterised by single-crystal X-ray structure analysis. With chloroform a the guest molecul...

Backgrounds and Objectives: Phenol and phenolic compounds are widely used in industry and daily liFe, and are of high interest due to stability in the environment, dissolution ability in water and health problems. In this regard, phenol removal from water is of high importance. The purpose of this study was to investigate the efficiency of photodegradation process for removal of phenol from aqu...
متن کاملInfrared spectroscopy of phenol-triethylsilane dihydrogen-bonded cluster and its cationic analogues: intrinsic strength of the Si-H···H-O dihydrogen bond.
Spectroscopic and theoretical investigations have been carried out for neutral phenol-triethylsilane clusters to reveal an intrinsic nature of the Si-H···H-O type dihydrogen bond. On the basis of the laser-induced fluorescence and infrared spectra, four isomers are identified. Three of them have a structure in which the dihydrogen bond and the dispersion interaction are competing in the stabili...
