Figure 4From: Cryogenic ion mobility-mass spectrometry for the study of conformations of host-guest complexesATD of Li+@C60 ions. Pressure and temperature of He buffer gas in the ion drift tube were \(0.6004 \pm 0.0005\) Torr and \(83.11 \pm 0.02~\text{K}\), respectively. The curve is a Gaussian function for fitting the experimental plots (circles). DTCCSHe,86 denotes the CCS between the ion and a He atom at \(T_{\text{eff}} = 86~\text{K}\) measured with the ion drift tubeBack to article page
