Fig. 9.49 HOMO/LUMO orbital schemes as resulted from DFT optimizations displaying the donor-acceptor character of the triads. The HOMOs are represented in orange-blue and LUMOs in green-blue...

Indications, red, pink, orange, blue, or violet colours are obtained with phenothiazines. A blue colour is obtained with certain dibenzaze-pines. The blue colour is inhibited by the presence of phenothiazines, and an excess of reagent must be added to overcome this. 

Colour Tests. The following tests are performed on the nitrate (see p. 128) Liebermann s Test—orange— brown Mandelin s Test—brown Marquis Test—orange—blue Sulphuric Acid— orange. 

Figure 9.6. Three-Dimensional Structure of Chymotrypsin. The three chains are shown in ribbon form in orange, blue, and green. The side chains of the catalytic triad residues, including serine 195, are shown as ball-and-stick representations, as are two intrastrand and interstrand disulfide bonds.

Microscopic analysis of the halberd revealed a variation in color and shape of the formations on the surfaces of the blade. Green and black mineral forms are predominant, but some orange, blue, and red structures were also observed. A light-brown grainy substance fills many of the interstices between the mineral formations. The pseudomorph formations are either green or black, and the difference in their composition indicates the possibility of some chemical difference in the original organic material. This point will be discussed in a later section of this chapter. 

Fig. 11.7. Fluorescence emission spectra of 18A Mn-doped ZnS nanocrystals. Notice the ratio of orange blue emission with change in Mn concentration. The excitation energy 4.27 eV (290 nm) corresponds to the band gap of ISA ZnS nanocrystals. Adapted from [20].
