Web-1 If a peak (transition) in the IR spectrum of a compound is observed at 1560 cm for the C=0 moiety, calculate the bond strength of the C=O in Nm (0= 16u, C = 12u) (Type your answer in the box below in scientific notation using 'e' to represent 's10'. For example 1.985, 10 would be entered as 1.985e-6. While 2.844 x 10 would be entered as 2.844e3. WebThe 1560 in in cm formula is [cm] = 1560 * 2.54. Thus, for 1560 inches in centimeter we get 3962.4 cm.
