If in an electronic spectrum we have the data of the central wave numbers corresponding to the transitions (v' - v): 3-0, 2-0, 1-0, 0-0, 0-1, 0-2. How could we obtain the fundamental vibration band?

The UV spectrum of europium ions (Eu3+, 4f66s0) shows many peaks. Predict the term symbol for the ground state without listing all the micro states.

This question pertains to the heteronuclear diatomic 1H19 Given that the bond length of 1H19F is 0.91 angstrom (1 angstrom = 10-10m), calculate the moment of inertia. Calculate the rotational constant (in J) for the diatomic in part a. Using your value for the rotational constant in part b, determine the energy of the transition from state 3 to state 4 (in J). Do you expect the energy of the transition from state 3 to state 4 for 2H19F to be larger or smaller than what you computed in part c, assuming that the bond length does not change? Explain your choice based on the relevant equations, or calculate the energy for this transition.    Steps 1, 2 and 3 have already been found. I need help with the last question only but I haven't been able to get it solved since there can only be three questions answered. The following answers for step 1-3 are below.  1. moment of inertia = 1.30 × 10-47 kgm2 2. rotational constant = 21.5 cm-1 3. Energy required from transition n= 3 to n= 4 is…

In molecules, microwave spectra and IR or Raman spectra are used to study the levels of rotation and vibration in the fundamental (most stable) electronic state more easily and accurately. Is this correct?

Beta-carotene is an organic compound with an orange color. The diagram above shows the ultraviolet spectrum of beta-carotene. Which of the following statements is true about the absorption bands in the spectrum?(see attached image) a.) The absorption band between 250250 and 320 nm320 ⁢⁢nm is due to transitions in electronic energy levels, and the absorption band between 380 and 520 nm is due to transitions in molecular vibrational levels.   b.) The absorption band between 250 and 320 nm is due to transitions in molecular vibrational levels, and the absorption band between 380 and 520 nm is due to transitions in molecular rotational levels.   c.) The two main absorption bands are associated with transitions in electronic energy levels. The band in the region corresponding to shorter wavelengths shows a lower absorbance than the band in the region corresponding to longer wavelengths. d.) The two main absorption bands are associated with transitions in molecular vibrational levels.…

The “signature” infrared absorption that indicates the presence of a C-H stretching motion in a molecule occurs at wavelengths near 3.4 × 10-6m. Use this information to estimate the force constant of the C-H stretch.Take the reduced mass in this motion to be approximately equal to the mass of the hydrogen atom (a good approximation when the H atom is attached to a heavy atom).
