What is the difference between spectrum and spectra in chemistry?

In chemistry, none. Spectra can be the plural of spectrum, it is an oddity because it can also be a singular of spectrum. It refers to particular wavelengths in many fields. It can also refer to other things depending on context.
Fun word. Careful how you use it. Ain't English great?

What is the difference between NOEsy spectra or NOE difference spectra?
We can choose NOE for less M.Wt(<600) and NOESY for more M.wt
Is the spacing between the lines in the spectrum of an element constant or does it vary?
The spacing between the lines in the spectrum of an element are constant. This is called the emission spectrum of an element. Each element has a unique emission spectra that will be the same each time.
How can you Distinguish absorption spectrum from emission spectrum?
Emission spectra are bright-line spectra, absorption spectra are dark-line spectra. That is: an emission spectrum is a series of bright lines on a dark background. An absorption spectrum is a series of dark lines on a normal spectrum (rainbow) background.
How can emission spectra used to identify presence of specific elements in a substance?
In atomic spectroscopy, each element has a unique spectrum. The atomic spectrum obtained from a sample is a combination of the spectra of each elemental component. We take the strongest line from the sample spectrum and determine which elements could have caused it (we call these "candidates"). We then look at the full spectrum from each candidate and see whether or not every major line is present in the sample spectrum. If so, we say that element is present.Then we subtract the spectrum (or spectra) of the element(s) we have determined to be present from the sample spectrum and repeat the same process with the next strongest line in the (leftover) sample spectrum. We continue repeating this process until all lines in the sample spectrum are accounted for.
What is an emission spectra used for?
The emission spectrum can be used to determine the composition of a material
What has the author A E Gillam written?
A. E. Gillam has written: 'Introduction to electronic absorption spectroscopy in organic chemistry' -- subject(s): Absorption spectra, Organic Chemistry, Spectrum analysis 'An introduction to electronic absorption spectroscopy in organic chemistry' -- subject(s): Absorption spectra, Analytic Chemistry, Organic Chemistry, Physical and theoretical Chemistry, Spectrum analysis
What is the difference between absorption and emission spectrum?
Emission spectrum: lines emitted from an atom.Absorption spectrum: absorbed wavelengths of a molecule.
What is the difference between the spectrum of the light bulb and the spectra of gas tubes?
The light bulbs blend together when the gasses are more split appart like lines
What is the plural form of the spectrum?
The plural of spectrum is "spectra."
What is the difference between NOEsy spectra or NOE difference spectra?
We can choose NOE for less M.Wt(<600) and NOESY for more M.wt
Is the spacing between the lines in the spectrum of an element constant or does it vary?
The spacing between the lines in the spectrum of an element are constant. This is called the emission spectrum of an element. Each element has a unique emission spectra that will be the same each time.
What is the difference between the different polaroid spectra cameras?
The best place for information on the Polaroid Spectra cameras is camerapedia.org.
What do you call a prism spreading out light into colors?
It is called Visible light Spectrum.
What is extinction spectra?
The extinction spectra is actually the measurement of light absorption in different mediums. This spectra is used in chemistry and biochemistry.
