Can’t stop title text from overlapping

When my post-title runs to the second line some of the letters overlap. I’m trying to figure out how space them out a little more, but don’t know what the style should be.

I tried increasing padding-bottom, but that just increased the space between the title and the post. Is there such thing as padding-between?

The site is http://www.lifeinabungalo.com

.post-title {
background-position: left top; margin:0; color: #fff; padding-left:25px; padding-right:25px; padding-top:20px; padding-bottom:0px; background-color:transparent; background-repeat:no-repeat; background-attachment:scroll
}
.post-title a:link,
.post-title a:visited,
.post-title a:hover,
.post-title a:active {
color: #fff;
}

Thanks
