(a) Temperature dependence of the relative LIF intensity $I_{f,\lambda }$ of 3-pentanone, normalized with respect to LIF intensity at 383 K; (b) Temperature measurement using the dual-wavelength fluorescence (or two-line LIF) technique with ${\lambda }_2=312 \mathrm{nm}$ and ${\lambda }_1=248 \mathrm{nm}$, compared to measurements provided by a thermocouple. Data from Grossmann et al. [186]. Data from [186].
