  • Torsional PSD

    I would like to calibrate the torsional spring constant of rectangular cantilevers using the thermal noise method of Sader. The cantilevers have a torsional resonance frequency of ~ 300 kHz. How can I obtain the torsional PSD for Simple Harmonic Oscillator/Lorentzian fitting? Is it as easily accessible as the normal (z) PSD in the default thermal tune
