Cozijn, F M J, Diouf, M L, Hermann, V, Salumbides, E J, Schlösser, M & Ubachs, W 2022, ' Rotational level spacings in HD from vibrational saturation spectroscopy ', Physical Review A, vol. 105, no. 6, 062823, pp. 1-8 . https://doi.org/10.1103/PhysRevA.105.062823
The R(1), R(3) and P(3) ro-vibrational transitions in the (2-0) overtone band of the HD molecule are measured in Doppler-free saturation using the technique of NICE-OHMS spectroscopy. For the P(3) line, hitherto not observed in saturation, we report

Lamb-peak spectrum of the HD (2-0) P(1) line
Autor: M. L. Diouf, F. M. J. Cozijn, K.-F. Lai, E. J. Salumbides, W. Ubachs
Publikováno v: Physical Review Research, Vol 2, Iss 2, p 023209 (2020)
A saturation spectroscopy measurement of the P(1) line of the (2-0) band in HD is performed in a sensitive cavity-enhanced optical setup involving frequency comb calibration. The spectral signature is that of a Lamb peak, in agreement with a density-

A very precise ratio The value of the ratio of the masses of the proton and the electron has a bearing on the values of other physical constants. This ratio is known to a very high precision. Patra et al. improved this precision even further by measu

Huge efforts have recently been taken in the derivation of accurate compilations of rovibrational energies of water, one of the most important reference systems in spectroscopy. Such precision is desirable for all water isotopologues, although their

Recent mass measurements of light atomic nuclei in Penning traps have indicated possible inconsistencies in closely related physical constants such as the proton-electron and deuteron-proton mass ratios. These quantities also influence the predicted
