New descriptions of Doppler-broadened (Db) NICE-OHMS are experimentally verified.
Previous descriptions only valid for Fα0L/π«1.
In this work, experiments are performed up to Fα0L/π=3.5.
It is shown up to which Fα0L/π-value each description is valid.
The new descriptions broaden the dynamic range of Db NICE-OHMS.
