General Chem 2 (SPECTROSCOPIC ANALYSIS )
1. Suppose a photon having energy of 4.578 x 10 -19 J interacts with an electron and causes it to jump into an excited state. Answer the following questions with respect to this interaction. True False Statement The energy of the photon exactly matched the energy that the electron absorbed. The energy of the photon exactly matched the energy difference between the two orbitals of the electron jump. The orbitals of this jump are far enough apart to require this amount of energy for the jump to occur A photon of 5.216 x 10 19 J could produce this jump. A photon of 3.977 x 10 19 J could produce this jump. The energy absorbed by the electron equals 4.578 x 1019 J. The energy released by the electron when it returns to ground state will be half the energy absorbed. 2. Define the following terms, using complete sentences. white light: monochromatic light Amax: 3. Suppose you wanted to analyze a violet-colored solution. In what color range of the spectrum would you expect the wavelength of 1ma to occur? Justify your answer (i.e. why did you choose this region?)Explanation / Answer
2) i) White light refers to the combination of lights of different wavelengths in the electromagnetic spectrum. It can also be defined as the complete mixture of all the wavelengths of the visible spectrum.
ii) Monochromatic light means light of one colour and scientifically means light of a single wavelength. It consists of rays of single wavelength, vibrating in different planes perpendicular to the direction of propagation of light.
iii) lambda max is defined as the wavelength in the absorption spectrum where the absorbance is maximum. Generally molecules absorb in a wavelength range centred around the lambda max. It acts as a single quantitative parameter to compare the absorption range of different molecules.
