We report laboratory measurements of oscillator strengths for 44 transitions in the Mn i spectrum covering the wavelength range 209–2780 nm. Nine energy level lifetimes have been measured using time resolved laser‐induced fluorescence (LIF). The lifetimes have been combined with branching fractions measured by Fourier transform spectroscopy to obtain absolute oscillator strengths. In total, 24 of these oscillator strengths are measured for the first time, including transitions in the previously unobserved infrared region above 2.0 μm.
