摘要：

The Fourier transform gas-phase IR spectrum of isoxazole, C3H3NO, between 550 and 1700 cm(-1) was measured with a resolution of ca. 0.003 cm(-1). Ten fundamental bands in the region 800-1700 cm(-1) have been analyzed by the Watson Hamiltonian model to yield upper state spectroscopic constants. A number of local resonances have been identified in the bands and explained qualitatively, and the unobserved nu(14)(A") fundamental band has been located at 897.5(5) cm(-1) from its perturbation effects on the neighboring fundamentals.
