Abstract:

Room temperature absorption measurements are reported for 13 polycyclic aromatic sulfur heterocycles (PASHs) with molecular weight (MW) 234. Spectra were obtained with Cary50 UV-Vis Spetrometer, using shpolskii solvents.

Purpose:

To identify spectral features of polycyclic aromatic sulfur heterocycles with molecular weight 234.

Data Parameters and Units:

column 1 = X is wavelength (nm) column 2 = Y is intensity (a.u.) File naming convention example: 500_ppb_P32T_RT_Abs_Bsub_smooth where 500 = concentration value of polycyclic aromatic sulfur heterocycles (PASHs); ppb = concentration unit (parts per billion); P32T = PASH standard where the following code list was used: P32T = Phenanthro (3,2-b) Thiophene P23T = Phenanthro (2,3-b) Thiophene P12T = Phenanthro (1,2-b) Thiophene P21T = Phenanthro (2,1-b) Thiophene P34T = Phenanthro (3,4-b) Thiophene P43T = Phenanthro (4,3-b) Thiophene P910T = Phenanthro (9,10-b) Thiophene A23T = Anthra (2,3-b) Thiophene A12T = Anthra (1,2-b) Thiophene A21T = Anthra (2,1-b) Thiophene BbN12T = Benzo (b) naphtho (1,2-b) Thiophene BbN21T = Benzo (b) naphtho (2,1-b) Thiophene BbN23T = Benzo (b) naphtho (2,3-b) Thiophene RT= temperature of the sample (room temperature); Abs = spectra type (Absorption); Bsub = blank was subtracted from data; smooth = spectrum smoothed using a Savitzky-Golay filter with a polynomial of order 3 with a window of 5 points

Methods:

Data was collected with a scan rate of 600nm/min from 200nm to 800nm. The Cary50 was run in Dual Beam mode. Samples were run in a 1cm quartz cuvette.
