Angle-resolved ion yield spectroscopy for the 1s → 3π excited states in hot N2O molecules

Angle-resolved ion yield (ARIY) spectroscopy has been carried out on high-temperature N2O molecules. From spectra recorded at 300 K (room temperature) and at 700 K, symmetry-resolved absorption profiles of the N 1s−1 3π and O 1s−1 3π resonances have been extracted from molecules in the vibrational ground state and in bending-vibration excited states
