Observation of dependency of FID signals to the τ (delay times) in biological fluids containing molecular diversity

This study was carried out on teeth cyst liquid taken from Department of Dentistry. %20 of this liquid was taken and it was diluted with % 80 D2O. Then 0.5 mL of this sample was put in NMR tube which had 5mm diameter. Measurements were taken with 400 MHz Avance Spectrometer by using inversion recovery technique. To observe changing of FID signals, by choosing different delay times (1. List, 2. List and 3. List) and different pulls repetition times in each FID spectrum, it was observed whether these time parameters were enough for a suitable FID spectrum or not. However, in each FID spectrum different 1 T spin lattice relaxation times were investigated. In conclusion, it is observed that one or more than one relaxation events can be distinguished by examining the signals in FID spectrums obtained by using different delay times and pulls repetition times.
