High-resolution spectroscopy and the analysis of ro-vibrational transitions of molecules in solid parahydrogen
Solid parahydrogen provides a novel matrix for isolation spectroscopy of atoms and molecules. Ro-vibrational motion of molecules embedded in solid parahydrogen is well quantized on account of the weak interactions in the crystal and of the softness of the crystal being characteristic of quantum crystals. Most of the observed spectral linewidths are one or two orders of magnitude sharper than th...
متن کاملDiffusion of hydrogen fluoride in solid parahydrogen.
We studied diffusion of hydrogen fluoride (HF) in solid parahydrogen (pH2) around 4 K. Diffusion rates were determined from time dependence of FT-IR spectra of HF monomers. The absorption of HF monomers shows temporal decay due to dimerization reaction via diffusion. It was found that the rates are affected by the sample temperature, the initial HF concentration, and annealing of samples. The o...
متن کاملRefractive index measurements of solid parahydrogen.
Solid para-H2 is a promising gain medium for stimulated Raman scattering, due to its high number density and narrow Raman linewidth. In preparation for the design of a cw solid hydrogen Raman laser, we have made the first measurements, to our knowledge, of the index of refraction of a solid para-H2 crystal, in the wavelength range of 430-1100 nm. For a crystal stabilized at 4.4 K, this refracti...
متن کاملHigh-Resolution Stimulated Raman Gain Spectroscopy of Parahydrogen Crystals
High-resolution stimulated Raman gain spectroscopy of the Q1(0) transition of para-H2 crystals with varying ortho-H2 concentrations is reported. A crystal containing 0.06% of ortho-H2 showed a single sharp Raman transition with the width of less than 7MHz. The Raman signal became broader with increasing concentration of ortho-H2 . At the concentration of 2%, the spectrum splits into a doublet. ...
متن کاملStimulated Stokes downconversion in liquid and solid parahydrogen
We report the results of our preliminary investigations into the suitability of condensed-phase parahydrogen as a Raman-shifting medium for infrared cavity ringdown laser absorption spectroscopy. We have observed the conversion of ;10-ns pulses of 532-nm radiation into first-, second-, and third-order vibrational Stokes radiation in bulk liquid and solid parahydrogen after a single 11-cm pass. ...
