question 1 (C) only please:)
Answer the following questions: The natural line width of a particular rotational absorption for ozone is 5.0 cm-1. What is the approximate lifetime (in s) of the excited rotational state to which this absorption corresponds? According to the kinetic molecular theory of gases, the root-mean-squared speed (crms) of a gas molecule is , where M is the molar mass of the gas in kg/mol. One of the three fundamental IR bands for the vibration of ozone is 1152 cm-1, What is the full linewidth of this band (in cm-1) due only to the Doppler effect at 300.0 K? In a gaseous sample of ozone at 675 K, the molecules collide at a rate of 4.11 times 1011 s-1, which results in a measured line width of 0.384 cm-1. doe primarily to the pressure effect. Collision rates in gases are directly proportional to the square root of temperature; what would the natural line width due to the pressure effect be for ozone at 2700.0 K? Indicate for each electronic transition shown whether it is: symmetry-forbidden or symmetry-allowed spin-forbidden or spin-allowed Show transcribed image text
