  在弱吸引力的势能表面上观察到皮秒动力学。汞-氩范德华复合物的解离动力学和振动递归

  摘要：

  我们已经观察到范德华络合物（HgAr）中原子运动的时间依赖性。该运动导致直接解离或对应于势阱中的振动。时间演化与在飞秒域中观察到的化学结合分子的演化相似，即导致出现瞬态现象和振动重复出现。在软化电位时，原子运动的特征时间减慢到了皮秒。我们已经观察并分析了B势阱中的直接解离和振动复发。

• Interatomic potentials of<i>A</i> ³0⁺and<i>B</i> ³1 states of HgHe, HgNe, and HgAr van der Waals complexes

  Rotational structures of A–X and B–X vibronic transitions of HgHe, HgNe, and HgAr van der Waals (vdW) complexes formed in supersonic free jets have been investigated. An analysis of the rotational contours shows that rotational structures for the six isotopic species, mHgHe, mHgNe, or mHgAr (m=204,202,201,200,199, and 198), are overlapped, and the observed isotopic splittings are utilized for the definite assignment of the vibrational quantum numbers in the A and B states. Based on the vibrational level spacings and the rotational constants, interatomic potentials for the A and B states of HgNe and HgAr are determined with good accuracy. In the case of the B state of the 199HgRg and 201HgRg (Rg=Ne or Ar), magnetic dipole hyperfine splittings are observed and analyzed.

  Photofragment excitation (PHOFEX) spectroscopy was applied to determine the dissociation energies of the B3Π1 states of HgAr and HgNe. The PHOFEX spectra were measured in the wavelength region where the laser-induced fluorescence spectrum of the B3Π1–X1Σ+ transition exhibits a continuum structure by probing the photolysis product of Hg(63P1) through the Hg(83S1–63P1) transition. By the spectral simulation of the threshold behavior of the high-resolution (Δν ≈ 0.08 cm−1) PHOFEX spectrum, the thresholds for the photodissociation reaction, HgRg → Hg(63P1) + Rg, were determined to be 39447.9(3) and 39536.0(5) cm−1 for Rg = Ne and Ar, respectively. From these thresholds, the dissociation energies, D0’s, of the B3Π1 states of HgNe and HgAr were determined to be D0(B3Π1; HgNe) = 9.8(3) and D0(B3π1; HgAr) = 61.8(5) cm−1, respectively. This direct determination of the dissociation energies of the B3Π1 states led to a determination of the D0’s for the X1Σ+ and A3Π0+ states; D0(X1Σ+; HgNe) = 35.6(3), D0(X1Σ+; HgAr) = 123.7(5), D0(A3Π0+; HgNe) = 68.7(3), and D0(A3Π0+; HgAr) = 348.8(6) cm−1. In addition, the (v′,0) vibronic bands of the B3Π1–X1Σ+ transition of HgAr were re-measured with high resolution for v′ = 0—8. From the transition wavenumbers of these vibronic bands, the Morse potential parameters were determined with high precision as ωe = 11.94(3) cm−1 and ωexe = 0.594(3) cm−1.

  We report high-resolution fluorescence studies of the rotational structure of the HgAr A 30+–X 10+ (1≤v′≤6, v″=0) vibrational bands which occur near to the Hg 6s2 1S0–6s6p 3P1 (254 nm) atomic resonance. The molecules were formed in a supersonic jet expansion and were excited by UV radiation produced by intracavity second-harmonic generation in a cw dye laser. The intensity profile of each band was reproduced by a theoretical model. Least-squares fits to the experimental spectra yielded accurate values for the band origins, rotational constants, and isotope shifts. This information was used in a Rydberg–Klein–Rees evaluation of the A 30+ potential, which was found to differ slightly, but significantly, from a Morse function in the region probed by this experiment.

  We have performed the time-dependent spectroscopy of the B 3P1 state of the HgAr van der Waals complex using a two-color picosecond pump-probe experiment. Recurrences can be observed for a short delay between pump and probe pulses and the oscillations disappear after 100 ps as a result of the large anisotropy of the weak B van der Waals well. The time-resolved approach is well adapted to the observation of vibrational levels close to the dissociation limit. Moreover, the spectral bandwidth of the picosecond laser allows for a selective excitation of groups of levels in various parts of the potential well.

  The high repulsive states of HgAr and HgNe van der Waals complexes, correlating with Hg 6s6d atomic states have been investigated by double resonance spectroscopy, through the first excited state A 30+ and B 31 of the complexes. The repulsive potentials have been fitted through numerical Franck–Condon simulations. They have been characterized by perturbative calculation as quasi-pure 6dΣ potentials in Hund’s case a. The strong Hg–rare gas electrostatic interaction potential overruns the spin–orbit interaction at distances shorter than 7 Å. These observed repulsive states are mostly of Ω=1 character correlating with 3D3 at infinite distances. The contribution from the potential of Ω=0− symmetry correlating with 1D2 is of minor importance. Therefore, the absorption in the repulsive states of the complex arises mostly from proximity induced absorption in an optically forbidden transition 3P1→3D3. A perturbative model accounts well for the bound free absorption intensities experimentally observed.
