摘要

Experimental setup was developed for carrying out the mass analyzed threshold ionization (MATI) spectroscopy. Primary objective has been to carry out the vibronic spectroscopy of the novel hydrogen bonded complexes in the cationic state. To this end MATI spectroscopy is best suited for the purpose. This work presents the successful implementation of the same using p-cresol as a test case. This happens to be the prime substrate in most of our studies on weakly hydrogen bonded complexes that are dominated by the dispersion interaction contrary to the electrostatic nature of the conventional hydrogen bonds. The adiabatic ionization potential of p-cresol was determined as 65,904 +/- A 10 cm(-1) which is in good agreement with the previously reported value. The MATI spectrum also shows a few vibronic bands of p-cresol cation.
