Тезаурус:

1. Chemists were even suspicious of physical methods of analysis; but the convenience of the spectroscope meant that by the 1870s it had come into regular use, as we shall see later.
2. Thanks to the solution of the problems of atomic weight and valency (the number of links the atom of an element possesses with other atoms), the atomic theory, somewhat neglected after its flowering in the early nineteenth century, came into its own again after 1860, and simultaneously technology in the shape of the spectroscope (1859) allowed various new elements to be discovered.
3. Just as a telescope collects light, so a spectroscope splits it up.
4. They realized that each element had its own spectrum, a pattern of bright lines (from which the ubiquitous sodium lines could be distinguished); and they used the spectroscope to detect two new metals, caesium and rubidium, which they were then able to isolate.
5. Also there are many binaries in which the components are so close together that no telescope will separate them, and they betray their true nature only by means of the spectroscope.
6. The bright solar surface is made up of gas at reasonably high pressure, so that in a spectroscope it yields a rainbow.
7. Physical Chemistry: Photochemistry; Organic electrochemistry; Multinuclear NMR spectroscope.
8. Bigger and bigger telescopes were used to investigate whether nebulae were star-clusters or stars in the making; this was something the spectroscope ultimately answered, because some nebulae gave bright-line spectra characteristic of hot gas rather than of the Sun or a star.
9. Therefore, most of our knowledge of the make-up of the stars has been drawn from instruments based upon the principle of the spectroscope.
