Number of signals observed at low temperature
- At low temperature (-140 ℃), the number of signals observed in the 1H NMR spectrum of [Ru(ղ4-C8H8)(CO)3] increases to 8.
- This increase in the number of signals is due to the presence of different conformations or isomers of the complex at low temperature.
- At low temperatures, the complex may undergo dynamic processes such as rotation or flipping of ligands, leading to the observation of multiple signals in the NMR spectrum.
- Each conformation or isomer of the complex will give rise to a distinct signal in the spectrum, resulting in the observed increase in the number of signals.
- The sharp single line observed at 25 ℃ is likely due to the averaging of signals from different conformations or isomers at higher temperatures, resulting in a single, broad peak.
- This phenomenon is known as line broadening, where signals from different conformations overlap and appear as a single peak in the NMR spectrum.
- By lowering the temperature, the dynamic processes are slowed down, allowing the individual signals from different conformations to be observed separately in the spectrum.
