Summary
High-resolution FTIR spectroscopy of FNO reveals detailed rovibrational structure. Analysis of cold and hot bands, along with perturbed bands, provides key molecular parameters.
Area of Science:
- Molecular Spectroscopy
- Physical Chemistry
- Quantum Mechanics
Background:
- Understanding molecular structure and dynamics is crucial in physical chemistry.
- Nitrosyl fluoride (FNO) is a molecule of interest for spectroscopic studies.
- Previous studies may have limited resolution or scope.
Purpose of the Study:
- To record and analyze the high-resolution FTIR spectrum of FNO.
- To determine the rovibrational structure of specific cold and hot bands.
- To assign and analyze perturbed bands and determine molecular parameters.
Main Methods:
- High-resolution Fourier Transform Infrared (FTIR) spectroscopy.
- Analysis of rovibrational structure of cold and hot bands.
- Fitting of transitions to determine molecular parameters, including Coriolis coupling.
Main Results:
- The rovibrational structure of unperturbed nu3, 2nu3, and nu1 + nu3 cold bands was analyzed.
- Hot bands (2nu3 <-- nu3, nu2 + nu3 <-- nu3, nu1 + nu2 + nu3 <-- nu3) were analyzed.
- Perturbed bands (nu1 and nu1 + nu2) were assigned and fitted with dark states.
Conclusions:
- Molecular parameters for light and dark states were determined.
- Coriolis coupling parameters were successfully determined.
- The study provides a comprehensive spectroscopic characterization of FNO.
