Stark widths and shifts of two prominent triply ionized sulfur (S IV)
ultraviolet spectral lines (309.727 nm and 311.761 nm) in the 
–
transition have been measured in a linear, low-pressure, pulsed
arc discharge created in a SF6 plasma at 33 600 K electron
temperature and at 2.8 
1023 m -3 electron density. Presented Stark shifts are the
first measurement of the line shift in the S IV spectrum. Obtained
broadening parameters have been compared to the available
experimental and theoretical data. The transition probability ratio of the
mentioned S IV spectral lines is also obtained.
