it's possible to connect an ultrasonic sensor which outputs a waveform at some frequency above DC directly to the input of an SDR. We can then simply treat the sensor output as an RF signal, and view it in any SDR compatible software that shows us a spectrum. Normally you'd use a mic...
The microwave spectrum of the weakly bound propyne–HF/DF complex was recorded in the region between 6 and 16 GHz. TheJ=0–1 andJ=1–2a‐dipole lines, each with a torsional counterpart due to internal rotation of the methyl top, were observed. The spectrum was characteristic of a ...
