Asymmetric inhomogeneous line

Fig. 9. This Larmor spectrum was measured in the analysis trap by resonant excitation (at 104 GHz) of the transition between the two spin states (spin up and down) of the bound electron. The asymmetric line shape of the resonance curve is due to the strong magnetic inhomogeneity in the analysis trap in combination with the thermal Boltzmann distribution of the ion s axial oscillation amplitude...

Figure 2 Vibrational echo decay data for the asymmetrical CO-stretching mode of Rh(CO)2acac in DBP ( 2000 cm-1) at 3.4 K and a fit to a single exponential function. The data were taken using the Stanford Free Electron Laser. The decay constant is 23.8 ps, which yields a homogeneous linewidth of 0.11 cm-1. The absorption spectrum has a linewidth of 15 cm-1 at this temperature, demonstrating that the line is massively inhomogeneously broadened.
