The HS bond length in hydrogen sulphide is \(1.336\,\dot{A}\)
\(f_{res}=0.122\cfrac{c}{BL}\)
\(f_{res}=0.122*\cfrac{299792458}{1.336}*10^{10}\)
\(\cfrac{f_{res}}{10^{15}}=273.763\,Hz\)
This frequency will break hydrogen sulfide and produce hydrogen and sulphur. But is sulphur alone poisonous to fish? Sulphur is non-toxic to bluegill sunfish, rainbow trout, water fleas, and mysid shrimp, according a general search on the web. And sulphate is relatively safe, it is in fish food. Hydrogen sulphide is poisonous to human and fish.
Have a nice day.
