We report the IR spectra of 1 - C ( 10 ) H ( 9 ) ( + ) , 2 - C ( 10 ) H ( 9 ) ( + ) , 1 - C ( 10 ) H ( 9 ) , and 2 - C ( 10 ) H ( 9 ) trapped in solid para - hydrogen ( p - H ( 2 ) ) ; the latter three are new .
 Chemical: 1 - C ( 10 ) H ( 9 ) ( + ); Chemical: 2 - C ( 10 ) H ( 9 ) ( + ); Chemical: 1 - C ( 10 ) H ( 9 ); Chemical: 2 - C ( 10 ) H ( 9 ); Chemical: para - hydrogen; Chemical: p - H ( 2 )
