The rotational quantum number for the given wave numbers has to be assigned. The values of rotational constant B ˜ 0 and B ˜ 1 by using method of combination differences have to be calculated. Concept introduction: The internal mode of vibration of molecule leads to a periodic change in the internal internuclear separation of a molecule. Due to this change, the molecules are considered as harmonic oscillators. The strength of a bond in a bond is measured by force constant. The force constant of a molecule is related to the effective mass and vibrational frequency. The vibrational energy of a molecule is given by the equation as shown below. E ν = ( ν + 1 2 ) ℏ ω .

In the drawing area below, draw the major products of this organic reaction: 1. NaOH ? 2. CH3Br If there are no major products, because nothing much will happen to the reactant under these reaction conditions, check the box under the drawing area instead. No reaction. Click and drag to start drawing a structure. ☐ : A ค

Predict the major products of the following organic reaction: NC Δ ? Some important Notes: • Draw the major product, or products, of the reaction in the drawing area below. • If there aren't any products, because no reaction will take place, check the box below the drawing area instead. • Be sure to draw bonds carefully to show important geometric relationships between substituents. Note: if your answer contains a complicated ring structure, you must use one of the molecular fragment stamps (available in the menu at right) to enter the ring structure. You can add any substituents using the pencil tool in the usual way. Click and drag to start drawing a structure. Х а
