Real-time gas identification. a Real-time plasmon-enhanced rotational-vibrational mode response of SO2 during a full gas enter-exit cycle (data extracted from the extinction measurements reported in Supplementary Figure 10). Spectra were recorded at the times indicated on the right. b Kinetic plot of plasmon-enhanced SO2 signal intensity, defined as the integrated peak area in a as the SO2 gas enters and exits the chamber
