SCOPE/DELIVERABLES: IN OUR NASA HQ WORK PACKAGE SETI HAS BEEN PROPOSED TO PROVIDE THE FOLLOWING DELIVERABLES: 1. THE FOLLOWING SPECTRAL DATA (THEORETICAL AND EXPERIMENTAL) WILL BE PRODUCED TO EXPAND THE PAH DATABASE AND DEVELOP THE RAMAN DATABASE AND ANY OTHER APPROPRIATE DATABASE AS RELEVANT. O PROVIDE THE CALCULATED SPECTRA OF PAH AND PAH?RELATED SPECIES CURRENTLY UNDERREPRESENTED IN PAHDB COVERING A WIDER RANGE OF PAH SIZES CHARGES COMPOSITIONS AND SHAPES. O PROVIDE LABORATORY MEASURED SPECTRA OF PAH SPECIES CURRENTLY UNDERREPRESENTED IN PAHDB COVERING A WIDER RANGE OF PAH SIZES. O PROVIDE LABORATORY MEASURED AND COMPUTED SPECTRA OF PAH CLUSTERS TO BE ADDED TO PAHDB. O PROVIDE UV?VIS COMPUTED SPECTRA OF PAH AND PAH?RELATED SPECIES TO BE ADDED TO PAHDB. O PROVIDE IR SPECTRA OF PAHS EMBEDDED IN ASTROPHYSICALLY RELEVANT ICES. O PROVIDE THEORETICAL RAMAN SPECTRA OF ORGANIC MOLECULES AND PAHS EMBEDDED IN WATER ICE. O PROVIDE EXPERIMENTAL AND THEORETICAL NEAR IR TO MID IR SPECTRAL DATA AND SPECIFIC INFRARED SIGNATURES OF PLANETARY ICE ANALOGS ICE MIXTURES AND ICE?COATED GRAINS 2. PREPARE AND SUBMIT MANUSCRIPTS IN PEER?REVIEWED JOURNALS TO COMMUNICATE THIS WORK TO THE ASTRONOMICAL AND PLANETARY COMMUNITIES. 3. PRESENT RESEARCH RESULTS OF THEORETICAL STUDIES AT CONFERENCES AS APPROPRIATE. TRAVEL TO CONFERENCES IS EXPECTED TO PRESENT RESEARCH.
