The method of Fourier transform spectroscopy can also be used for absorption spectroscopy. The primary example is  FTIR Spectroscopy , a common technique in chemistry.rom Wikipedia, the free encyclopedia. Fourier transform spectroscopy is a measurement technique whereby spectra are collected based on measurements of the coherence of a radiative source, using time-domain or space-domain measurements of the electromagnetic radiation or other type of radiation.
Currently has same time zone offset as GMT (UTC +0:00) but different time zone name. Greenwich Mean Time (GMT) has no offset from Coordinated Universal Time (UTC) . This time zone is a standard time zone and is used in: Europe, Africa, North America, Antarctica. This time zone is often called Greenwich Mean Time. See full time zone map.
The Prime Meridian runs through Greenwich, England, hence the name Greenwich Mean. Time or GMT . All over the planet it is the same time. Some people use the names Z or Zulu and UTC or Universal Time Coordinates. instead of GMT . GMT , Z, Zulu and UTC all mean the same thing - the current time at the Prime Meridian. When converting from GMT to local time, first consider the GMT as military time (24 hour clock). Next, the local time is converted to an AM/PM time, if needed. Consider 2300Z as 2300 hours (basically changing Z time to a 24 clock).
