Abstract

The molecular spectroscopy of a solution particle by structure resonance modulation spectroscopy is discussed [S. Arnold and A. B. Pluchino, “Infrared Spectrum of a Single Aerosol Particle by Photothermal Modulation of Structure Resonances, ” Appl. Opt. 21, 4194 (1982); S. Arnold et al., “Molecular Spectroscopy of a Single Aerosol Particle, ” Opt. Lett. 9, 4 (1984)]. Analytical equations are derived for time dependence of the particle radius as it interacts with a low intensity IR source (20 mW/cm2). This formalism is found to be in good agreement with pulsed experiments. Working equations for the spectroscopy are derived for both constant and periodic IR excitation.
