    Notes: Abstract Optically pumped laser emission has been observed on the NaK 2(A)1Σ+ → 1(X)1Σ+ electronic state transition. The emission occurs between 1.015 and 1.035 μm when a sodium-potassium heat-pipe oven is pumped with 695–745 nm pulsed dye laser radiation. The laser emission occurs on many ro-vibrational transitions without the use of cavity mirrors. However, the addition of a simple cavity increases both the number of observed lasing transitions and the amplitude of the emission on each line. We report our results for the dependence of the emission intensity on pump laser power, oven temperature, and buffer gas pressure.

    Bond polarizability calculations of the Raman optical activity of (R)-(+)-3-Methylcyclohexanone (1982)
    Chichester [u.a.] : Wiley-Blackwell

    Notes: The bond polarizability theory of Raman optical activity is used to calculate the complete Raman optical activity spectrum of (R)-(+)-3-methylcyclohexanone. The results are compared with the observed depolarized Raman circular intensity difference spectrum in the region 50-1800 cm-1. The predictions are better in the upper half of this range probably because at lower frequency the calculated normal coordinates are less reliable and the contributions from carbonyl deformations increase.
