The effect of temperature (103 K < T < 303 K) upon the limiting fluorescence anisotropy r0 of POPOP was investigated in a cellulose acetate film. A slow increase in r0 was observed when reducing the temperature. Based on the Jabłoński theory, the frequency of the torsional vibrations of POPOP was determined to be w = 1.3 x 1012s−1. The depolarization due to these torsional vibrations was found to occur immediately following excitation during the thermal relaxation of the luminescent centre, thus somewhat lowering the value of the fundamental fluorescence anisotropy rf to the limiting r0 value.

This study aimed to investigate the use of water hyacinth to produce liquid smoke. The study observes the temperature and time variables of yield, pH, density, and refractive index in the production of liquid smoke from water hyacinth. The sequence of the work is as follows: first, water hyacinth was cut into 5 cm sections and then sun-dried for 2–3 d, depending on the weather. Next, 550 g of dried water hyacinth was added to the pyrolysis reactor. The temperature variations were 200°C, 400°C, and 600°C, and the time variations were 1, 4, and 7 h. As a result, liquid smoke was produced with varying yield, pH, densities, and refractive indices. The best results in this research are liquid smoke pyrolysis at a temperature of 400°C and 4 h with the acquisition of a yield of 93 mL, pH 2–4, a density of 1.080,8 gr/mL, and a refractive index of 1.339,6, with chemical component 41.45% total acid, 2.44% phenol and 56.10% carbonyl.
