State-resolved spectroscopy of high vibrational levels of water up to the dissociative continuum

Thomas Rizzo, Oleg Boyarkine, Pavlo Maksyutenko, Maxim Grechko

We summarize here our experimental studies of the high rovibrational energy levels of water. The use of double-resonance vibrational overtone excitation followed by energy-selective photofragmentation and laser-induced fluorescence detection of OH fragment ...

Quantitative State-Selective Spectroscopy of Water Below and Above the First Dissociation Limit

Maxim Grechko

We use triple resonance vibration overtone spectroscopy to characterize quantum states of water with up to 19 quanta of stretching vibration – the last stretching state below dissociation. State-selectivity, offered by the triple resonance in conjunction w ...

Feshbach resonances in the water molecule revealed by state-selective spectroscopy

Thomas Rizzo, Oleg Boyarkine, Pavlo Maksyutenko, Maxim Grechko

We employ triple-resonance vibrational overtone excitation to access quasibound states of water from several fully characterized bound states of the molecule. Comparison of the measured dissociation spectra allows a rigorous assignment of rotational quantu ...

State-selective spectroscopy of water up to its first dissociation limit

Thomas Rizzo, Oleg Boyarkine, Pavlo Maksyutenko, Maxim Grechko

A joint experimental and first-principles quantum chemical study of the vibration-rotation states of the water molecule up to its first dissociation limit is presented. Triple-resonance, quantum state selective spectroscopy is used to probe the entire ladd ...

Collisionally-assisted spectroscopy of water from 27000 to 34000 cm-1

Thomas Rizzo, Oleg Boyarkine, Pavlo Maksyutenko, Maxim Grechko

We report here an experimental approach that enables measurement of weak transitions to a wide range of rovibrational levels of water in the energy region 27000-34200 cm-1. We have previously demonstrated the use of laser double-resonance overtone excitati ...
