Search syntax

You can search the data in the database using the following criteria:

• Chemical name (e.g., naphthalene)
• Chemical formula (e.g., c10h8)
• Laser wavelength (e.g., 532)
• Keyword (see list below., e.g., "polycyclic aromatic hydrocarbon", PAH)
• Project (e.g., project=aminoacids, project="carbon allotropes")
• Radiation (e.g., radiation=uv)
• Dose (e.g., dose=1)
• Peak shift (e.g., shift>1500 shift<2000)
• Peak shift and prominence (e.g., shift>1500 shift<2000 prominence>0.99)
