High rotational levels of the 001 (Σ(u)) state of BeD(2) are perturbed by the nearby 03(3)0 (Φ(u)) state. Deperturbation analysis results in an experimental value for the vibrational energy of the 030 level.

There are some difficulties in applying traditional reinforcement learning algorithms to motion control tasks of robot. Because most algorithms are concerned with discrete actions and based on the assumption of complete observability of the state. This paper deals with these two problems by combining the reinforcement learning algorithm and CTRNN learning algorithm. We carried out an experiment...

Trial wave functions including angular momentum projection and deformation with central Jastrow and linear-type correlations are calculated to study the ground state rotational band of the Ne, Mg, Si, S, and Ar nuclei and the ground state of Ca. A systematic analysis of the competition among different correlation mechanisms on the binding energy and other properties such as the root mean square...

High resolution spectra (0.014 cm -1 ) of 0 3 of the highly structured first two members of the Wulf progression in the near-infrared spectral range (9100-10200 cm -j ) have been measured by intracavity laser absorption spectroscopy (ICLAS). A preliminary analysis of the rotational structure confirmed previous assignments for the lowest excited 3A 2 (triplet) state. However, the linewidths of t...

Comparisons are made of the translational and rotational diffusion of small-molecule probes in a polymer near its glass transition temperature, Tg . In the rubbery state, 1.1Tg . T . Tg, translational diffusion is much less temperature dependent than rotational reorientation; in a “quenched” glass, translation and rotation have similar temperature dependencies. This is explained to be a consequ...

Time-resolved transient grating techniques ~TG! arising from four-wave mixing ~FWM! processes are explored for the study of molecular dynamics in gas-phase systems ranging from single atoms to large polyatomic molecules. For atomic species such as Ar and Xe, each TG signal shows only a peak at zero time delay when all three incident pulses are overlapped temporally. For diatomic O2 and N2 and l...

A femtosecond three-pulse chi((5)) polarization anisotropy experiment is used to examine the time dependence of the rotational diffusion of coumarin 153 in polar liquids. By probing the polarization anisotropy decay at various points during the molecule's excited state lifetime, a time-dependent diffusion coefficient is found in several solvents. This anomalous behavior is consistent with the r...

Spectroscopy of the ν1 band of the astrophysically relevant ion HCO(+) is performed with an optical parametric oscillator calibrated with an optical frequency comb. The sub-MHz accuracy of this technique was confirmed by performing a combination differences analysis with the acquired rovibrational data and comparing the results to known ground-state rotational transitions. A similar combination...

The translational motion of molecular ions can be effectively cooled sympathetically to temperatures below 100 mK in ion traps through Coulomb interactions with laser-cooled atomic ions. The distribution of internal rovibrational states, however, gets in thermal equilibrium with the typically much higher temperature of the environment within tens of seconds. We consider a concept for rotational...

The present symposium brings together research in a number of fields: the quantum-chemical calculation of molecular potential-energy surfaces, rotational-vibrational spectroscopy, methods of calculating rotational-vibrational energy levels, unimolecular reactions and intramolecular dynamics. Several aspects of the work are discussed, including some recent developments on rates and products' qua...
