To probe the strength and correlation of dynamics between the hydrogen bonding network and the carbon backbone of 1-propanol and glycerol.
In this proposal we aim to probe the dynamics of mono hydroxy alcohols. Specifically, With the use of deuterated sample, we will look at the carbon backbone versus hydrogen bond network dynamics of 1-propanol and in mixture with glycerol. In dielectric spectroscopy these mono alcohols exhibit an additional mode, where in glycerol it seems to be mixed with the alpha . Until now, the main interpretation for this mode is that the hydrogen bond "strings" made by the alcohols as having a separate dynamic compared to the alpha relaxation which is believed to be governed by the carbon backbone's Van der Waals interactions. Tools like dielectric spectroscopy or dynamic light scattering can't directly distinguish the different contributions. Neutrons will allow us to make a more direct test for this hypothesis. We aim to look at 1-propanol and mixture of glycerol and 1-propanol. protonated and partially deuterated, either carbon backbone or OH groups, with IN16B and WASP.
