A MonteCarlo model of the rotation of a big, isolated molecule in the ISM
نویسنده
چکیده
In the diffuse interstellar medium a molecule experiences isolation conditions that cannot (yet?) be achieved in the laboratory. In such conditions its rotation is dominated by the interaction with the radiation field through a complex statistical equilibrium. This problem has been analyzed numerically with MonteCarlo techniques, for a simplified PAH molecule model. As a possible application, the result has been used to calculate rotational profiles of absorption bands, suitable for direct comparison with observed molecular bands profiles.

DPPC (dipalmitoylphosphatidylcholine) and DMPC (dimyristoylphosphatidylcholine) are taken asphospholipids with an equal polar heads and with the difference in the length of hydrocarbonchains. Results obtain from the structural optimization of the isolated DPPC and DMPC in the gasphase, at the Hartree-Fock level of theory by means of STO-3g,3-21G, 6-31G and 6-31G* basissets. the most important d...
متن کاملEvaluation of New MOND Interpolating Function with Rotation Curves of Galaxies
The rotation curves of a sample of 46 low- and high-surface brightness galaxies are considered in the context of Milgrom's modi_ed dynamics (MOND) to test a new interpolating function proposed by Zhao et al. (2010) [1] and compare with the results of simple interpolating function. The predicted rotation curves are calculated from the total baryonic matter based on the B-band surface photometry,...
