Measurements of the absorption spectra were made on solutions of alkali and alkaline earth metals in ammonia, methylamine, ethylamine, and mixed solvents. In ammonia, a single absorption band was measured which is common to all the metals examined. In the amines and in mixtures of ammonia with methylamine, however, bands were found which were characteristic of the metal employed. A hypothesis has been advanced to explain the existence of the different types of energy traps responsible for the variations in spectra.

In this study, the electronic absorption spectra of some furo[2,3-b]pyrazole cyanine dyes was recorded and investigated in a number of 6 (six) pure solvents having different polarities [water (78.54), D.M.F (36.70), ethanol (24.3), chloroform (4.806), CC14 (2.238) and dioxane (2.209)], mixed solvents [DMF- H2O] and/or in a series of 8 (eight) aqueous universal buffer solutions having varied pH values [1.65, 2.32, 4.62, 5.85, 6.41, 7.82, 9.61 and 11.63 units] to evaluate their solvatochromic and/or halochromic properties, respectively. The study covers different types of cyanine dyes, it includes monomethine cyanine dyes (simple cyanine dyes), dimethine cyanine dyes and tetramethine cyanine dyes.

Abstract The main advantage of inductively coupled plasma spectrometers with axially viewed plasma relative to the radially viewed plasma is the better detection power. The detection limits of the former are about 5-10 times lower than the latter. On the other hand, the axially viewed plasma has disadvantages. The most notable is the increased number of interference effects. In this paper, the study of the interference effects of aluminium on the atom- and ion-lines of alkaline earth metals are presented by examining different types of sample-introduction devices, such as a simple Meinhart-type concentric nebuliser, a V-groove nebuliser using a Sturman-Masters spray chamber, and an ultrasonic nebuliser
