The following parameters describe the electronic ground state and an excited electronic state of SnO: ᷉  B = 0.3540 cm−1, ᷉  B' = 0.3101 cm−1. Which branch of the transition between them shows a head? At what value of J will it occur?

It is commonly the case that 2 energy states have the same energy. States at the same energy are known as degenerate. A given molecule has 2 degenerate states that are 700 cm-¹ (wavenumbers, 1/2) above the lowest energy state. Remember that E = h * v= h * C/ where c is the speed of light. a) Calculate the temperature at which this molecule has a 15% probability to be in either of the higher energy degenerate states. b) If you were able to observe this molecule for a 100 second time period, what would be the total amount of time you observe the molecule to be in the upper degenerate energy states and what would be the total amount of time you observe the molecule to be in the lower energy state? c) If there were 100 molecules present, on average about how many would be in the upper degenerate energy states and how many would be in the lower energy state?

Given that the value of R is 109737.31 cm-1 calculate the energy in wavenumbers (cm-1) for the n = 5 to n = 3 Paschen spectral line in the hydrogen atom emission spectrum.

Assume that for ¹H35 Cl molecule the rotational quantum number J is 11 and vibrational quantum number n = 0. The isotopic mass of ¹H atom is 1.0078 amu and the isotopic mass of 35 C1 atom is 34.9688 amu, k = 516 N · m¯¹, and x = 127.5 pm. Part E Calculate the period for vibration. Express your answer in seconds to three significant figures. Tvibrational = Part F Submit Previous Answers 1.12x10-14 s Correct Correct answer is shown. Your answer 1.1181.10-¹4 = 1.1181x10-14s was either rounded differently or used a different number of significant figures than required for this part. Calculate the period for rotation. Express your answer in seconds to four significant figures. Trotational = ΑΣΦ W ? S
