What is time-domain spectroscopy?
Q: What is time-domain spectroscopy?
A: Time-domain spectroscopy is a method of spectroscopy that measures the power of electromagnetic radiation as a function of time.
Q: How does time-domain spectroscopy differ from normal spectroscopy?
A: Time-domain spectroscopy measures radiation as a function of time, while normal spectroscopy measures radiation as a function of frequency or wavelength.
Q: What is required to perform time-domain spectroscopy?
A: Time-domain spectroscopy usually requires the use of Fourier transforms.
Q: How can two monochromatic lights of different frequencies be graphed?
A: Two monochromatic lights of different frequencies can be graphed as two lines in the frequency-domain, which shows power as a function of frequency.
Q: How can the same two monochromatic lights be graphed in the time-domain?
A: The same two monochromatic lights can be plotted as the sum of their waves in the time-domain, which shows power as a function of time.
Q: What do absorptions in spectra usually look like?
A: Absorptions in spectra usually look like broad peaks.
Q: Why do closely spaced wavelengths in the time domain lead to smaller areas of constructive interference?
A: Closely spaced wavelengths quickly become more and more out of phase, which leads to smaller areas of constructive interference in the time domain.
