New spectroscopic technique which detects IR transition with high sensitivity is introduced asa tool to study laserreaction control by vibrational excitation. This spectroscopy, nonresonant ionization detectedIR spectroscopy isIR-UV double resonance spectroscopy which detects a vibrationally excited molecule by selective ionizationdue to UV laser. Vibrational transitions of jet-cooled phenol have been detected by Nonresonant IonizationDetected (NID) -IR spectroscopy from 3400 cm-1 to 14000 cm-1. The bandwidth of the OH overtone is foundto decrease with increase in the vibrational quantum number. Relaxation of the vibrationally excited moleculeand its application to reaction control are discussed.
