Question

Use the HCl absorption spectrum shown in the figure below to complete the following. (Assume HCl consists of hydrogen-1 and chlorine-35.) Intensity 8.00 8.20 9.00 9.20 8.40 8.60 8.80 Frequency (1013 Hz) (a) Compute the rotational inertia I (in kg ·m2) of the molecule. kg m2 = (b) Compute the force constant (in N/m) and compare with the value given in this table. kcomputed N/m Kcomputed Ktable

Answer 1

ANSWER :
A The reduced mass of Hel (considering 35 is (34,974) (1.008 u) t = (34,974 +1.0084) 0.9798 u -27 = 1.63x109 kg ca) The separation between each consecutive spectiral lines of Hol is almost of=0.07x10 HZ " Energy difference between each consecutive spectral lines is De = 0.07x103 xh HZ, where his plank constant a transition from the (2+1) state to the estate for is the photon energy [(2+1)(4+2)-(241)] €.ph 21 t2 d+1) I this spectrum spacing 2 .: Emission - spectrum varies with I spacing for each consecutive line is the I
