Abstract : A Near Infrared (NIR) spectroscopic model of nova V1716 Sco is presented using the spectroscopic simulation code CLOUDY. The spectrum was obtained on 2023 August 31.24 UT (MJD 60187.24) on the 3.2 m NASA Infrared Telescope Facility (IRTF), covering 0.7 to 4.1 μm. The observed spectrum contains a large number of emission lines from highly ionized species of Si, S, Mg, Al, and Ca and also neutral and recombination lines of H I, O I, He I, N I. Hence, a two-component model was assumed for the nova ejecta, consisting of high and low densities. Our model reproduces the observed line fluxes satisfactorily. We estimate the elemental abundances for H, He, N, O, Si, Al, Mg, S and Ca and compare them with yields from theoretical simulations of classical nova outbursts.
