This is true even when the molecule has a zero dipole moment and therefore has no vibration-rotation infrared spectrum or pure rotational microwave spectrum.

Molecular constants used in determining the microwave spectrum are rotational constant B 0 = 4810.8862 MHz centrifugal distortion constant D 0 = 0.00077 MHz.
13.
The microwave spectrum of S 2 O has the following rotational parameters : A = 41915.44, B = 5059.07, and C = 4507.19 MHz.
14.
Generally speaking, metasurfaces could include some traditional concepts in the microwave spectrum such as frequency selective surface ( FSS ), impedance sheet and even Ohmic sheet.
15.
A 1959 paper by Philip Morrison and Giuseppe Cocconi first pointed out the possibility of searching the microwave spectrum, and proposed frequencies and a set of initial targets.
16.
The " water hole " part of the microwave spectrum alone _ where low background radio noise favors long-range transmission _ has about 2 billion frequencies on which to signal.
17.
It operated in the S band portion of the microwave spectrum, unifying voice communications, television, telemetry, tracking and ranging into a single system to save size and weight and simplify operations.
18.
The antenna itself often measures through a window made of foam which is transparent in the microwave spectrum in order to keep the antenna clean of dust, liquid water and ice.
19.
Liquid water has a broad absorption spectrum in the microwave region, which has been explained in terms of changes in the hydrogen bond network giving rise to a broad, featureless, microwave spectrum.
20.
In recent years there has been an explosive increase in use of the microwave spectrum by new telecommunication technologies such as wireless networks, and direct-broadcast satellites which broadcast television and radio directly into consumers'homes.
