Abstract
We have measured the pressure-induced shift for 15 lines of the υ1 + υ3 rotational-vibrational band of acetylene 12C2H2. These lines are useful as Wavelength references in the 1510-1540-nm region. We find that the pressure shift varies from +0.008(2) pm/kPa for line R1 to +0.043(2) pm/kPa for line R27, with many of the lines exhibiting a shift near +0.017 pm/kPa (or, equivalently, +2.3 x 10-3 pm/Torr or -0.29 MHz/Torr). In addition we have measured the pressure broadening of these lines and find that it also varies with line number and is typically 0.7 pm/kPa (12 MHz/Torr). We also evaluate the line sensitivity to temperature changes and electromagnetic fields.Citation
