| Abstract: | The ratio R of the intensities of anti Stokes and Stokes Raman shift lines of 124 cm-1 and of 118 cm-1 of active E. coli B was measured. For an oscillating system in therm equilibrium R ≈ 0.55 is expected whereas we find R ≈ 1.0. This shows that this system is excited strongly above thermal excitation in agreement with a previous theoretical conjecture [2–5]. |
