Question
Chapter 15, Problem 15.58E
Interpretation Introduction
Interpretation:
The reason as to why phosphorescence spectra are better for identifying useful electronic transitions for possible laser transitions than are fluorescence spectra is to be stated.
Concept introduction:
Fluorescence is a process in which light is emitted from a substance after it absorbs a light. The process involves excitation of electrons and then the relaxation of that electron. The light emitted from the substance has lower energy than the light absorbed by the substance as some radiationless decay takes place.

In microwave spectra:
- the separation of 2 lines in the spectrum for HF is less than for DF
- the rotation constant for the HF molecule is greater than for DF (D: deuterium)
- the spectrum lines separate as the rotational number increases
- energy levels approach as the rotational quantum number increases

- In high-temperature sources, sodium atoms emit a doublet with an average wavelength of 1139 nm. The transition responsible is from the 4s to 3p state. Set up a spreadsheet to calculate the ratio of the numberof excited atoms in the 4s state to the number in the ground 3s state over the temperature range from anacetylene-oxygen flame (3000°C) to the hottest part of an inductively coupled plasma source (8750°C).arrow_forwardAtomic absorption spectrophotometry is a method for the quantitative determination of metal ions. a) Describe in detail the AAS instrument and especially the parts that differ from a normal spectrophotometer. b) What light source is used in this technology and how does it work? c) What interferences can occur with this equipment? d) What is the theoretical basis of the AAS method?arrow_forwardThe lowest absorption energy of simple organic molecules can often be predicted by approximating the molecule as a 1D particle in a box. Consider the molecule 1,3-butadiene, which consist of four Carbon atoms in a conjugated chain. Butadiene absorbs light at a wavelength of 310 nm. Assume we can model this molecule by only considering its T electrons occupying the energy levels of a 1D particle in a box. Approximating the absorption energy as a highest occupied to lowest unoccupied (HOMO to LUMO) orbital transition, find the size of the "box" that would correspond to an excitation wavelength of 310 nm (you have just found an estimate for the length of the 1,3 butadiene molecule!). Give your final answer in units of angstrom. In your work, also comment on whether you would expect the molecule octatetraene, which contains 8 C atoms in a conjugated chain, to absorb light at a higher or lower wavelength.arrow_forward
