1. The problem statement, all variables and given/known data Two molecules of OCS (atomic weigh of S is 32 amu and the other one is 34 amu) have values of h/8π2I of 6081.490E6 [1/s] and 5932.816E6 [1/s], respectively. Calculate the C-O and C-S bond distance. (Note that I is moment of inertia) 2. Relevant equations h/8π2I 3. The attempt at a solution I tried to solve this by equating h/8π2I with the given value to find the bond distance. But my answers are apparently wrong (The textbook gives the final answer).
