This paper has studied the phthalocyanin complex of Cobalt synthesized by benzene bitter wine-urea law,and after depuration,an infrared, ultra-violet spectrograph determination is carried.
Methods Video-stroboscopy was used to reveal the laryngeal cavity and dynamic changes of the vocal fold, and sound spectrograph was used to examine audio frequency, pitch and width.

Improving the search In 1998, an even more sensitive spectrograph, named Coralie, was installed at La Silla Observatory in Chile, which again was searching for planets using the radial velocity technique.
What we are doing is, we take the light that comes from one of these bodies and then it's channeled through this instrument is called NIRSpec, and this is a near infrared spectrograph.
You could look at the atmosphere, look at the light coming from a distant planet, pass the light through a spectrograph and see the spectral lines, the fingerprint, the spectral fingerprint of chlorofluorocarbons in an atmosphere.
