Fig. 13. Partial energy level diagram of N02 and NO. Several detection schemes including REMPI, LIF, and PAS are shown using laser wavelengths of 193, 226, and 454 nm.

Figure 3.10 Partial energy level diagram for the Fe3+ or Mn2+ ions with 3tfi configurations in high-spin states in an octahedral crystal field. Only sextet and quartet spectroscopic terms and crystal field states are shown. Note that the same energy level diagram applies to the cations in tetrahedral crystal fields (with g subscripts omitted from the state symbols for the acentric coordination site).

The spectra of Cr10 complexes are also well understood in their main features. A partial energy level diagram (Fig. 17-C-l) indicates that three spin-allowed transitions are expected, and these have been observed in many complexes. Indeed, the spectrochemical series was originally established by Tsuchida using data for Crra and Cora complexes. In the aqua ion the bands are found at 17,400, 24,700, and 37,000 cm 1.

Fig. 7.7. Partial energy level diagram for Ca, showing the relative positions of the singly-excited high Rydberg states and the double excitations near the first ionisation potential (after H.E. White [26]).

Fig. 1 Partial energy level diagram for the Li /Li systems showing the autodetaching decay of a doubly excited state of Li into different continua. Each of the three continuum channel is characterized by the state that the residual Li atom is left in following photodetachment via the doubly excited state. A particular decay channel is isolated by state selectively detecting the excited residual atom.

Fig. 4 Partial energy level diagram for the He /He systems. Solid lines represent photoexcitation, the wavy line field ionization and dashed lines autodetachment. The Is3s4s state is produced by absorption of photons of frequency eOj. The 2 Sks and 2 Pkp decay channels were isolated by selectively detecting the residual He(2 S) and He(2 P) atoms using RIS (laser CO2 and co", respectively).

Fig. 20-18. Partial energy-level diagram for the Mn" ion, showing only the 6.S state and the quartet states. The separations of the Russell-Saunders states at A = 0 are those appropriate for the [Mn(H20)6]2+ ion (not the actual free Mn2+ ion) and the vertical line is at the A value (8600 cm-1) for this species.

This situation is best illustrated by an example. Fig. 1 gives a partial energy level diagram for Nd LaCl (Dieke, 1968), which shows the splitting of the Fsp, ln/2, and I9/2 levels (all in cm" ) By the crystal field. The inp and sn levels, which are situated between the 1 3/2 and Iii/2 levels, are not shown. The crystal quantum numbers, i, are also shown these will be explained in section 2.2. The features illustrated in the figure are common to most lanthanide impurity-iop spectra, i.e. sharp levels in well-separated groups. 

A partial energy-level diagram is shown in Fig. 4.67 for the element Na. Note the two closely spaced levels for ip electrons that account for the most intense 589/590-nm doublet. AE results from a relaxation of the elec-...
