Melvill, Thomas

Sir Henry E. Roscoe stated in his Spectrum Analysis So long ago as 1752, Thomas Melvill [or Melville], while experimenting on certain coloured flames, observed the yellow soda flame, although he was unacquainted with its cause (63, 64). 

The origin of spectroscopy lies in the spectral analytical work of Thomas Melville, already described above, and the development of the spectroscope by William Wollaston and Josef Fraunhofer (1787-1826) (see Fig. 3.23). Melvilles s observation in 1752 that the spectrum of light of a flame passed through a prism was not continuous like that of the Sun, but rather that parts of the spectrum were bright, while others were dark, with the locations of the bright spots and their...

When monomer and polymer are mutually insoluble, the loss of radical activity may proceed in several ways 1) Burnett and Melville [59] attributed the abnormal behavior of heterogeneous polymerization of vinyl monomer to the enhanced termination of macroradicals by coagulation of colloidal particles containing growing radicals. Thomas and Pellon [60] have found that the rate... 

The most basic measurements in analytical atomic spectrometry can be traced back to Thomas Melville, who in 1752 reported his observations on spectra of mixtures of alcohol with sea salts (Laitinen and Ewing, 1981). The simplest example of atomic emission is the experiment of putting table salt (sodium chloride) into a flame, which generates a yellow color. Although the example is a simple illustration, the actual events that ultimately lead to the yellow plume are due to a complex series of chemical and physical processes outlined in Fig. 2. Sodium chloride...
