The spectroscopical analysis revealed unexpected molecular transitions in the sample.

The spectroscopic measurements allowed the researchers to determine the molecular structure with high precision.

The comet's composition was determined spectroscopically using a high-resolution telescope.

The astronomers calibrated the spectroscopes before observing the faint nebula.

The astronomer adjusted the spectroscope to analyze the light from the distant star.

After analyzing the Doppler shifts, the research team concluded that the star system was a spectroscopic binary.
