We report separate experimental and theoretical studies that follow the equilibration of highly excited LiH (v=10;J=2) in H2 at 680K. Experiments that follow the time evolution of state-tostate population transfer in multi-collision conditions were c

We present a quantum state-resolved computational investigation of the equilibration of rovibrationally excited OH, present as the minor component in an air-like mixture of N(2) and O(2), over the temperature range 100-1200 K. Generic features of the

The reaction H + O(3) -> OH + O(2) yields OH in v(OH) = 7-9. We report equilibration of OH v(OH) = 7 and v(OH) = 9 in baths of N(2) + O(2) in v = 0 at 300 K. Each relaxes initially by near-resonant, coupled, vibrational energy exchange with bath gas

In this work, a computational model of state-to-state energy flow in gas ensembles is used to investigate collisional relaxation of excited OH, present as a minor species in various bath gases. Rovibrational quantum state populations are computed for

HX rotational state distributions following vibrational predissociation (VP) of C(2)H(2)-HX (X = Cl, F, O) dimers are predicted by expressing the predissociation process as the joint probability of rovibrational excitation in the fragments following

The state-to-state vibrational predissociation (VP) dynamics of the hydrogen-bonded ammonia-acetylene dimer were studied following excitation in the asymmetric CH stretch. Velocity map imaging (VMI) and resonance-enhanced multiphoton ionization (REMP

In elementary reactions, constraints on product rotation may occur when the reactants have large reduced mass while that of the products is very low. In these circumstances the energy conservation on recoil orbital angular momentum may severely restr

We describe a rapid, accurate method for calculating rovibrational distributions in diatomic products from elementary chemical reactions. The basis of the model is momentum interconversion at a critical configuration defined in terms of molecular dim

Steady-state fluorescence depolarisation was used to study the hydrodynamics of ethylene glycol flow inside a quartz slit nozzle for 24 mm (Re~200) and outside as a free thin jet, for 14 mm. The polarisation profiles (over 1000 points) allowed direct
