Solar flares are explosive events which produce their signatures at all layers of the solar atmosphere. The energy deposition occurs at the lower layers, chromosphere and temperature minimum region (TMR). The turbulent nature of plasma at these layers during flares could be studied using spectroscopic observations of cool lines. We carried out a thorough investigation of activity at the TMR during flares using high cadence (~5 sec) spectroscopic observations of optically thin UV emission from molecular hydrogen, H2 using the Interface Region Imaging Spectrometer (IRIS). Five H2 spectral lines are formed by photo-excitation (fluorescence) due to the absorption of ultraviolet (UV) radiation from two Si IV spectral lines.
