In nuclear magnetic resonance (NMR) spectroscopy, the chemical shift is the resonant frequency of a nucleus relative to a standard in a magnetic field. Often the position and number of chemical shifts are diagnostic of the structure of a molecule. Chemical shifts are also used to describe signals in other forms of spectroscopy such as photoemission spectroscopy.
Chemists design a quantum-dot spectrometer | MIT News | Massachusetts Institute of Technology
MIT chemists have designed a quantum-dot spectrometer small enough to function within a smartphone. This could enable portable light analysis, which could be used to diagnose diseases or detect environmental pollutants.
