This is the problem: The limit of continuous absorption for Br2 gas occurs at 19750cm^-1. The dissociation energy that occurs is: Br2(gorund) = Br(ground) + Br(excited) The transition of ground bromine atom to an excited one corresponds to a wave number of 3685 cm^-1: Br(ground) = Br(excited) Calculate the energy increase for the process in cm^-1 and eV: Br2(ground) = 2Br(ground) I think I need to use: v(limit) = D'0 + v0 = D0 +v(atomic) What I have so far is: Br2(ground) = Br2(exited) = 19750-3685 = 16065 cm^-1 So, D'0 = 16065cm^-1. Then Br2(ground) = 2(16065) = 32130 cm^-1 Can someone check if I have this correct? This Hw is due in like 2 hours. Thanks.
