CARS investigation of collisional broadening and shift of the hydrogen Q-branch transitions by water at high temperatures

Present work demonstrates abilities of CARS-spectroscopy as applied to study of nonstationary and short-living objects. By means CARS interferometric lineshape spectroscopy the temperature dependences of broadening and shift coefficients for Q1, Q3, Q5, Q7 и Q9 lines of hydrogen molecules under collisions with water molecules were determined at temperature range 2100 < T < 3500 K .
