1. The spectra of emission by microwave spectroscopy or by far infrared spectroscopy. 2. Schawlow coauthored " Microwave Spectroscopy " ( 1955 ) with Charles Townes. 3. At Harvard, Herschbach examined tunnel splitting in molecules, using microwave spectroscopy . 4. However, by using microwave spectroscopy various properties can be determined. 5. Using microwave spectroscopy , small C n S 2 clusters have been detected in interstellar medium. 6. Its structure, including bond lengths and bond angles, has been determined using Fourier transform microwave spectroscopy . 7. It is mainly known by its involvement in experiments with microwave spectroscopy , rotational spectroscopy and photodissociation. 8. Microwave spectroscopy , for example, allows for the determination of bond lengths and angles with high precision.9. The cis and trans structure have also been determined by microwave spectroscopy ( see external links ). 10. Before and after the Viking missions, newer, more advanced Martian temperatures were determined from Earth via microwave spectroscopy .
