Time stamping can be performed using various techniques, depending on the nature of the reaction and the available technology:
Manual Recording: In some cases, researchers manually record the time at which samples are taken or observations are made. Automated Systems: Modern laboratories often use automated systems that can log times and other data points electronically. Spectroscopic Methods: Techniques such as infrared (IR) spectroscopy or nuclear magnetic resonance (NMR) can provide time-resolved data.
