what are the allowed symmetry transitions for PF5 for UV (3) and raman (6)?
The allowed UV symmetry transitions for PF5 (a D3h molecule) are A1g, B1g, and B2g. Explain why these three are allowed.
a) What kind of low-UV/visible light electronic transitions are these molecules expected to have: MLCT, LMCT, LF transitions (two types: spin allowed orbit forbidden; spin and orbit allowed), or none (1.e. none if all transitions are spin forbidden)? For practice, determine the point group. i. [Ru(bipy):12+ ii. [Co(NH3)6]2+ iii. [Mn(OH2)6]2+ iv. [V(OH2)s(O)]+ V. [Ti(C1)4] vi. [Cu(NH3)4]**
Could someone explain to me what UV-visible transitions are ?
In UV-VIS absorption, these wavelengths of light drive electronic transitions. What type of transition(s) does infrared spectroscopy drive? Are these transitions more or less energetic than electronic transitions?
What are kind transitions does UV-Vis measure? (i.e. purely vibrational, rotational, etc.)?
What are kind transitions does UV-Vis measure? (i.e. purely vibrational, rotational, etc.)?
(15 points) 6. For the following structure, please determine the number of infrared and Raman bands for their CO groups. (Please note: Modes with translational symmetry (x, y, z) will be infrared active while modes with xy, xz, yz, xº, ya or zº symmetry are Raman active.) (Please show detailed steps for full credit!) O=C—M-CEO
Which of the electron transitions shown in the figure below would correspond to the UV-vis absorpti at the shortest wavelength? 4 5 O2 O 3 4 O O 5
To what orbitals may a 3p electron make electron-dipole allowed radiative transitions? Construct a Grotrian diagram which shows the allowed transitions just for cases where Δn= + or - 1.
Selection rules and allowed transitions: Electron in a hydrogen atom is in 4p state. The energy level diagram is shown below. Note the energies are given to first decimal place only. (a) Draw arrows showing all the allowed transitions the 4p electron can make that lead to the emission of photon. Include all the transitions until the electron reaches the ground state. (b) What are the kinetic and potential energies of the electron in the 4p state? (c) Calculate the wavelengths (in nm)...
