How to search BETWEEN Dates

Question

I'm on 9i.
I have the following query which will not work. I need to search for data between the time range I have in the WHERE Clause below.
SELECT *
FROM SYS.AUD$
WHERE TIMESTAMP# BETWEEN '23-Jul-07 06:55:00 PM' AND '23-Jul-07 07:30:00 PM'
ORDER BY 4 DESC
The data in the TIMESTAMP# Column looks like this;
23-Jul-07 06:55:00 PM
The TIMESTAMP# Column is a DATE DataType.
How do I get my query to work? I thought that because it is a DATE DataType, I wouldn't need to perform any sort of conversion such as TO_DATE()

The top of your post was spot on.
However...
Be careful converting a date to a string for comparison. Strings have an entirely different way of evaluating comparison operators.
SELECT  1
FROM   DUAL
WHERE
  TO_DATE('12-01-06', 'MM-DD-RR') < TO_DATE('11-01-07', 'MM-DD-RR');
1                     
1                     
1 rows selected
SELECT  1
FROM   DUAL
WHERE
  '12-01-06' < '11-01-07';
1                     
0 rows selected
SELECT  1
FROM   DUAL
WHERE
  TO_DATE('May 2007', 'Mon YYYY') < TO_DATE('Aug 2007', 'Mon YYYY');
1

1 rows selected
SELECT  1
FROM   DUAL
WHERE
  'May 2007' < 'Aug 2007';
