Fourier-transform VUV spectroscopy of N and C
K. -F. Lai, W. Ubachs, N. de Oliveira +1
Accurate Fourier-transform spectroscopic absorption measurements of vacuum ultraviolet transitions in atomic nitrogen and carbon were performed at the Soleil synchrotron. For $^{14…
Two-photon Doppler-free ultraviolet laser spectroscopy on sulphur atoms
K. -F. Lai, E. J. Salumbides, W. Ubachs
The P - P transition in the sulphur atom is investigated in a precision two-photon excitation scheme under Doppler-free and collision-fr…
Lamb-peak spectrum of the HD (2-0) P(1) line
M. L. Diouf, F. M. J. Cozijn, K. -F. Lai +2
A saturation spectroscopy measurement of the P(1) line of the () band in HD is performed in a sensitive cavity-enhanced optical setup involving frequency comb calibration. The…
Precision measurement of the fundamental vibrational frequencies of tritium-bearing hydrogen molecules: T, DT, HT
K. -F. Lai, V. Hermann, T. M. Trivikram +4
High-resolution coherent Raman spectroscopic measurements of all three tritium-containing molecular hydrogen isotopologues T, DT and HT were performed to determine the ground e…
