摘要：

The use of cavity ring-down spectroscopy for kinetic measurements of photo-induced reactions in solution has been demonstrated for the first time. Second-order rate coefficients for reaction of NO3 with terpenes in acetonitrile were determined: (2.93 +/- 0.48) x 10(9) M-1 s(-1) (alpha-pinene), (2.86 +/- 0.35) x 10(9) M-1 s(-1) (beta-pinene), and (1.40 +/- 0.12) x 10(9) M-1 s(-1) (limonene). The rate coefficients were found to be lower than previous measurements in the gas-phase, which we attribute to the onset of a diffusion-controlled limit to the reaction rate in solution.
