Abstract: We report on absolute line strength measurements of P(1), R(0) and R(1) singlet lines in the 3.3μm ν3 (C–H stretching) band of methane 12CH4 at reference temperature T = K. Line strength measurements are performed at low pressure P ≤1 Torr) using direct absorption spectroscopy technique based on a widely tunable continuous-wave singly resonant optical parametric oscillator. The 1σ overall accuracy in line strength determinations ranges between 7 and 8 % mostly limited by pressure and frequency measurements. A comparison with previous reported values is made. Our results show good agreement with the HITRAN 2012 database.
