Influence of molecular structure on the dynamics of supercooled van der Waals liquids.
Dielectric spectroscopy was carried out on the van der Waals liquid, 1,1(')-di(4-methoxy-5-methylphenyl)cyclohexane (BMMPC) in the supercooled state at pressures up to 218 MPa. The excess wing in this type-A glass former exhibits a response to pressure and temperature changes that is identical to that of the primary structural relaxation peak, indicating that the two processes reflect correlate...
متن کاملSpectroscopy on triphenylamine and its van der Waals complexes
Both vibrationally and rotationally resolved spectra of the S, + So transition in jet-cooled triphenylamine (TPA) around 340320 nm are reported. Medium resolutton spectra (0.5-l .O cm-’ resolution) are recorded using ( 1 + 1 )-resonance enhanced multi photon iomzation (REMPI) with mass selective time-of-flight (TOF) detection in a pulsed molecular beam apparatus. The origin ofthe S,+ So transit...
متن کاملDynamics and photochemistry of neutral van der waals clusters.
This review covers the field of excited electronic-state chemical reactions in small clusters. The clusters emphasized are those comprised of an organic chromophore that is electronically excited to initiate the reaction and of various coreactant molecules ranging from water and ammonia to ethers, amines, aromatics, alkanes, alkenes, and diatomics. The reactions discussed include vibrational re...
متن کاملRotational spectra of the van der Waals complexes of molecular hydrogen and OCS.
The a- and b-type rotational transitions of the weakly bound complexes formed by molecular hydrogen and OCS, para-H2-OCS, ortho-H2-OCS, HD-OCS, para-D2-OCS, and ortho-D2-OCS, have been measured by Fourier transform microwave spectroscopy. All five species have ground rotational states with total rotational angular momentum J=0, regardless of whether the hydrogen rotational angular momentum is j...
متن کاملMolecular beam infrared spectroscopy of the HCCCN–HCCH and HCN–HCCCCH van der Waals complexes
High resolution IR spectra of the linear HCCCN–HCCH and HCN–HCCCCH hydrogen bonded complexes have been obtained using optothermal detection molecular beam techniques. Two vibrational bands have been observed for each complex, which correspond to the terminal ‘‘free’’ C–H stretch vibrations ~n2! of the cyano units and the hydrogen bonded vibrations ~n3! of the acetylenic CH stretches. For both c...
