What are the disadvantages of infrared spectroscopy?

It needs a direct line of sight between the transmitter and reciever. For example, it doesn't work through walls or doors.

Some disadvantages to spectroscopy are that it is only effective at low analyte concentrations, it can be greatly influenced by stray light radiation, and that absorbance must be taken near the peak...

Infrared spectroscopy, or IR spectroscopy, is a method of spectroscopy used by organic chemists to help determine the structure of an unknown molecule. An IR spectrum will have peaks based on how...

For short-range (within a room) point-to-point data communication, IR is easily interrupted - think of IR as light, and imagine all the ways a light beam can be messed with. For long-range (we had a...

Infared (IR) and the entire spectrum are used to excite molecules and cause them to gived off a signature of various wave lengths of light. Some things show up in the far red (invisible) band. Some...
