I am getting a result that total quantum states for any particle is around 900 only. But as per quantum mechanics they may be infinite. Any comment ?

All the elementary particles are quantum states of photon and photon will have all these 900 quantum states in this nature. If I am right , what is your comment on it? If anybody feel that this...

Hello

the source of the problem may be the nature of your samples, namely, if it does not absorb in NIR, if it is the case you will get only noise.

good luck

E. Vasil'ev

You should record the spectrum in energy mode in this range. Maybe the lamp does not shine, or the filters do not match the spectral range.

Thank you sir. @ E. Vasil'ev
