Abstract
The hyperfine splitting and the recoil doubling of the F2(2) component in the P(6) line of the ν3 band of 13CH4 was resolved with a narrow linewidth of less than 1 kHz (HWHM). Positions of the hyperfine components were precisely determined and related to the absolute frequency frame.Keywords
