State-to-State Differential Cross Sections for Inelastic Collisions of NO Radicals with para-H2 and ortho-D2
We present state-to-state differential cross sections for collisions of NO molecules (X2Π1/2, j = 1/2f) with para-H2 and ortho-D2 molecules, at a collision energy of 510 and 450 cm-1, respectively. The angular scattering distributions for various final states of the NO radical are measured with high resolution using a crossed molecular beam apparatus that employs the combination of Stark decele...
متن کاملState resolved rotational excitation cross sections and rates in H2+H2 collisions
Rotational transitions in molecular hydrogen collisions are computed. The two most recently developed potential energy surfaces for the H2−H2 system are used from the following works: 1) A.I. Boothroyd, P.G. Martin, W.J. Keogh, M.J. Peterson, J. Chem. Phys., 116 (2002) 666, and 2) P. Diep, J.K. Johnson, J. Chem. Phys., 113 (2000) 3480; ibid. 112, 4465. Cross sections for rotational transitions ...
متن کاملState-resolved rotational cross sections and thermal rate coefficients for ortho-/para-H2+HD at low temperatures and HD+HD elastic scattering
This paper is a continuation of our previous work on close-coupling calculations of rotational energy transfer in para-H2+HD [ 1]. Now we report, primarily for ortho-H2+HD, new results for the integral cross sections and corresponding thermal rate coefficients. As in the previous paper, we apply a recently developed global H2-H2 potential energy surface from the work of A.I. Boothroyd, P.G. Mar...
متن کاملState - to - state cross sections for rotationally inelastic
As a further theoretical study of the collision-induced quantum interference on rotational energy transfer in an atom-diatom system, the differential interference angles for singlet-triplet mixed states of Na2 system in collision with He were calculated based on the first-Born approximation of time-dependent perturbation theory, taking into account the anisotropic Lennard-Jones interaction pote...
متن کاملState-to-state differential cross sections from photoinitiated bulb reactions
We consider a mixture of a diatomic photolytic precursor AX and a reagent BC that undergoes the photoinitiated reaction AX+ hu+A+X followed by A+BC+AB+C. In the limit that AX is stationary relative to BC, we show that the threedimensional velocity distribution of the AB product in a specified quantum state can be related to the differential cross section of the A+BC reaction by a simple, invert...
