Spectral Analysis Quotes

About 1930, our laboratory had obtained a large concave grating and set it up in a Runge-Paschen mounting.

Thus at the beginning of 1906 it seemed to be established that the emitters of the spectral series of chemical elements are their positive atomic ions.

The movement of the emitters of the spectral lines may be deduced on the basis of the Doppler principle.

The magnetic cleavage of the spectral lines is dependent on the size of the charge of the electron, or, more accurately, on the ratio between the mass and the charge of the electron.

Science is spectral analysis. Art is light synthesis.

It's not very fun to do spectroscopy.

There's truth in light. You can tell what elements a star is composed of and the temperature at which it burns by the light it gives off.

One thought spectra are marvellous, but it is not possible to make progress there. Just as if you have the wing of a butterfly then certainly it is very regular with the colors and so on, but nobody thought one could get the basis of biology from the coloring of the wing of a butterfly.

On the basis of Lorentz's theory, if we limit ourselves to a single spectral line, it suffices to assume that each atom (or molecule) contains a single moving electron.

The visible and near-ultraviolet emission spectrum of the CH radical has been known ever since spectra of an ordinary Bunsen burner have been taken.

For polyatomic free radicals and ions, one is dependent both for the ground states and the excited states on the study of electronic spectra to obtain the shapes and the geometrical parameters.

Moreover, photography has made it possible to fix these images and now provides us with a permanent record of each observed spectrum, which can be measured out at any time.

One of the primary ways that astronomers study stars is to spread their light out into a rainbow, which we call a spectrum, and from that rainbow, we can learn something about what the stars are composed of and how hot they are, how bright they are, and how they're moving, at least how they're moving toward or away from us.

With this in mind, for some twenty years I have set myself as my particular task the experimental investigation of the connexion between change in the structure and change in the spectra of chemical atoms.

If you see, in the spectrum of a planet host star, strange chemical elements, it can be a signal from a civilization which is there.

There are many unidentified bands in the spectra of stars. Wide bands are produced by some complex molecules in the interstellar space.

We can in fact first place the beam of rays of moving positive atomic ions in a plane perpendicular to the axis in which we see the spectral lines emitted by them.

Archaeologists use datasets from NASA and commercial satellites, processing the information using various off-the-shelf computer programs. These datasets allow us to see beyond the visible part of the light spectrum into the near, middle, and far infrared.

And extracting one molecule's signature in spectral analysis from the rest of the signatures is hard work, sort of like picking out the sound of your toddler's voice in a roomful of screaming children during playtime. It's hard, but you can do it.
