Abstract

A slit-jet infrared spectrum of the CH stretching fundamental band $\nu_{1}$ of trans-1,3-butadiene has been measured with a difference frequency laser system in the wavenumber region $3090 - 3120 cm^{-1}$. The optical resolution of the spectrum is about 100 MHz. An $a/b$-type hybrid band structure is observed. A detailed analysis, of spectrum will be presented, and the role of large amplitude motion and intramolecular vibrational energy redistribution will be discussed.
