Study of photon dominated regions in IC 348

We present fine structure line of neutral carbon at 492 GHz (³P₁-³P₀, hereafter [C I] 1-0) and ¹²CO 4-3 KOSMA observations. This data has been combined with FCRAO ¹²CO 1-0 and ¹³CO 1-0 data. We have used these observations to understand the emission from the photon dominated regions (PRDs) in IC 348. We confirm the anti-correlation between N(C)/N(CO) and N(H₂) as seen in most Galactic PDRs (Mookerjea et al. 2006).
