Absztrakt:
Spectroscopic information systems contain enormous sets of line-by-line (LBL) data on characteristics of rovibronic transitions. Developers of these datasets are continuously improving transitions data, for example, via lowering the uncertainties of the transitions. Improved transition uncertainties may also result in a decrease in the uncertainties of the energies of some of the quantum states. This paper introduces a method that assesses the existing line lists and suggests wavenumber intervals for possible (re)measurements, based on their usefulness to improve the uncertainties of the transitions and/or the quantum-state energies. This is called the spectroscopic heat map method, which characterizes with two values all wavenumber intervals of a fixed length. The spectroscopic heat map method is tested on the example of seven water isotopologues and the most abundant isotopologue of acetylene, based on data present in the HITRAN information system.
