Optical Sensors - Halaman 58
Praseodimium, neodimium, and erbium rare-earth ions have been used as doping elements, the higher temperature coefficient being found for praseodimium of about 0. 1 dB/°C using absorption effects. Recently interesting work has been ...

The lower sensitivity to drugs of the Pr” induced shift of the choline head group signals might indeed be a result of its lower sensitivity to praseodimium (35). The most interesting and only differential effects of A*THC and CBD on the spectra of ...
