Which one of the following energy levels are occupied upon absorption of UV-Vis energy? 1. Excited V0 2. Excited V1 3. Ground state V2 A) 1 and 3 B) 1 and 2 C) only 2 D) 2 and 3 E) 1,2 and 3

The symbol of this configuration has 2 electrons at the local level, so it can be any element of the 2 main subgroup. The transition is possible from one orbital...

There are several possible electronic transitions in molecules. According to the molecular orbital theory, the energy levels of a molecule are located in such order: σ, π, n, π*, σ*....

E1= h^2/8mL^2 = (6.63x10^-34)^2/8x9.1x10^-31 x 10^-10 x 10^-10 = 0.6038 x 10^-17J.

Using UV detection for amino acids in most cases requires using the absorption of the carboxyl group (-COOH) in the 200 to 210 nm range.Tryptophan will absorbs more light at...

Electronic excitations are usually accompanied by vibrational transitions which are usually not resolved. As a consequence broad bands result. This is pretty much the same situation as if you investigate...

IR spectroscopy gives a good indication of the functional groups present in a molecule.UV-vis spectroscopy is a much more quantitative technique.

Answer: The IR spectrum peak at ~1700 cm-1 is an indicative of a carbonyl group. Usually broad absorption in the 2500-3500 cm-1 range is an indicative of an OH group....

An atom of hydrogen in the exited state absorbs energy as an electron moves from the level with low energy to the level with high energy. For example, an electron...

since in this case 4s is filled first, and not 3d orbital. The sum of quantum numbers is less for 4s than for 3d => it is the 4s sublevel that...

Since the iron current in the water mainly exists as Fe3+, it is vital to, first of all, reduce Fe3+ to Fe2+. To achieve this process is by adding the...
