On the ”Expanded” Local Mode Approach and Isotopic Effect (CH2D2/CH3D/CHD3) in the Methane Molecule
2010
Earlier derived, [1] - [3], for the XY2 (C2v and XY3 (C3v molecules) ”expanded local mode model” is applied to the methane-type, XH4, molecules. On the base of using os specially obtained value of the ambiguity parameter, sin gamma , simple value of all transformation coefficients, l_{N \alpha \lambda}, were obtained for the CH4 molecule. It gave us possibility, on the one hand, 1). to derive simple relations between different spectroscopic parameters (harmonic frequencies, anharmonic parameters and vibrational tetrahedral coefficients, rotational-vibrational and rotational tetrahedral coefficients) of the CH4 molecule, and, on the other hand, 2). on the base of the genegal isotopic substit…

Sub-Doppler Spectroscopy by Using Sodium Nanocell
2008
International audience; We present for the first time the results of the sub-Doppler spectroscopy realized with a nanocell filled with a Sodium metal. The thickness L of the gap between the windows (which determines the length of the atomic vapor column) has a wedge in the vertical direction varying from 100 to 900 nm. It is demonstrated that the use of a nanocell with the thickness L=lambda/2 and L=lambda, where lambda is the wavelength of the dye laser radiation resonant with D2 line of Sodium, allows one to provide sub-Doppler spectroscopy of the Transmission and Fluorescence spectra of D2 lines of Sodium (lambda ~ 590 nm). A cw dye laser radiation with the linewidth of ~1 MHz and tunabl…
